I've got QQ on my computer but I was wondering if I could go to Precise from Quantal without reinstallation.

Yep Yep and Hoh-hoi

In my opinion, it is the same as for 12.04 vs. 11.10, you can't downgrade.

http://ubuntuforums.org/showthread.php?t=1903087

But maybe there is a way I don't know of.

At this early point of development (only a couple of Quantal packages published) it is possible to downgrade to Precise.
You need to manually download the Precise version of every single package you have upgraded to Quantal. Perhaps from 10 to 20 packages.
Then, (for example with terminal) go to the folder they were downloaded to and run this:

sudo dpkg -i *.deb

I'm no expert, so I have no idea how to locate the upgraded packages and then install the Precise version of each of those.

if you know when you upgraded , open synaptic , then go to file>history that should tell you the names of the upgraded packages . You would probably be better off backing up your /home and doing a reinstall though , downgrades can get really messy . back up your /home anyway .

Well, after all, sorry to say this but you should have upgraded to Quantal only if you were an expert.

This suggestion is entirely experimental. I have never done it. You might be the first to try.

First of all, do you have another version of Ubuntu that you can boot into if something goes wrong.

I have an 11.10 that I use a standby. I have 12.04 on another partition that I have now begun converting to 12.10.

In a few days, when the rush has died down, I shall upgrade my 11.10 to 12.04 and it will be my standby as I use this 12.04/12.10.

These were the two commands that I used to convert a 12.04 to 12.10


sudo sed -i 's/precise/quantal/g' /etc/apt/sources.list


sudo apt-get update && sudo apt-get dist-upgrade

You could reverse the first command to


sudo sed -i 's/quantal/precise/g' /etc/apt/sources.list

and then run


[CODE]sudo apt-get update

if that don't work try


sudo apt-get upgrade

By changing the repositories to quantal and then updating and upgrading we brought in the packages that were available in the quantal repositories.

Now, by changing the repositories back to precise you may find that what was brought in is removed. I am sure that you will need to put your repositories back to precise.

But as I say, none of this is based upon experience.

Regards.

I've only been testing future releases once before, and that was for 12.04,in which you could not downgrade unless you reinstalled, therefore i never learned how to downgrade. On the other hand I do know some shell, and everyone has to start somewhere.

backup your personal data and the do a fresh installation of Precise.

Less hassle and since the start of this thread you could have been back up and running in precise ;)

Also it is less likely to cause issues.

Peace

Aw, man. There should be an easy up/downgrade, I think i'll just edit root instead.

There is. Backup whatever you want, and then take your yy.mm.iso and then do a fresh install. There is nothing else as easy and simple as that.

Thanks for everyone's input, it's just that a bunch of applications won't install or won't work because i'm in 12.10, I guess i'll just stay in QQ.

There is going to be breakage, especially being the first release after an LTS release. If this is your daily use system and you aren't at least multibooting, you are probably going to regret staying.

Really, try the pinning approach from my link. The earlier you start, the higher the chance of success.

@codingman
There are other visual methods, like Software Center, Synaptics, etc. But you can get the list of all installed packages in specific dates and ranges by regexp matching against your dpkg log.

Example: This will list all packages you have installed from Apr. 26th to today.

Name of packages in the range

[03:26:49] ahsl@AL-DESK01:[~]: cat /var/log/dpkg.log | grep "^2012-04-\(26\|27\|28\|29\|30\).*\ installed\ "

Number of packages in the range

[03:27:52] ahsl@AL-DESK01:[~]: cat /var/log/dpkg.log | grep "^2012-04-\(26\|27\\|28\|29\|30\).*\ installed\ " | wc -l
139

In my case, there are 139 packages. But I installed optional stuff. A normal update will likely have less updated packages.

Looking at the installed packages, I can easily see stuff I can remove without causing any system impact. Probably half of it.

If you're not sure how a package impacts your setup, you can see what packages depend on it, what it depends on, what it provides, using dpkg-query. Example (for package smbfs):

[03:29:20] ahsl@AL-DESK01:[~]: dpkg-query -W -f='Depends:${Depends}\nPre-Depends:${Pre-Depends}\nProvides:${Provides}\n' smbfs
Depends:cifs-utils (= 2:5.1-1ubuntu1)
Pre-Depends:
Provides:

Then you could even put in all together and automatically get the list of depends, pre-depends, provides for each of the packages you have installed in the date range:

[03:31:48] ahsl@AL-DESK01:[~]: for PACKAGE in $(cat /var/log/dpkg.log | grep "^2012-04-\(26\|27\\|28\|29\|30\).*\ installed\ " | awk 'BEGIN {FS=" "} {print $5}'); do echo "${PACKAGE}"; dpkg-query -W -f='Depends:${Depends}\nPre-Depends:${Pre-Depends}\nProvides:${Provides}\n\n' ${PACKAGE}; done

That can probably help a little.

Effenberg

Probably also working:
dpkg --get-selections | grep -P "\tinstall$" | awk '{print $1}' | sed "s/$/\/precise/" | tr '\n' ' ' to get a list of installed packages that I can feed to
sudo apt-get install

This will throw errors like
E: Release 'precise' for '<PACKAGE>' was not found - just remove those packages from the list and you should be good to go.

Good idea. I was also thinking about aptitude. If he tries to remove the packages installed from release day to today via Aptitude, but keep only precise repos in sources.list, wouldn't aptitude provide those "options" to solve dependencies (using --full-resolver)?

This is a "development" forum and "unstable" Quantal is still very much in flux and will be for months.

Expect to re-install frequently (!) I use test partitions for development and have a stable release partition for recovery.

On one pc where I don't want the Windoze....7 to be blasted I use a USB hard drive for testing. It's a left over laptop hard drive in a $10 case from Tiger Direct. Once the "unstable" release settles down I'll take the risk and try multibooting "unstable" to see if Grub xx will still allow booting the Windoze....7.

Better get into practice on install. And install. And re-install.

Good luck,

Jerry

Only prob is:

No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu quantal (development branch)
Release: 12.10
Codename: quantal
ventrical@ventrical1ME051:~$

and Quantal still comes up hard coded in System Monitor.. thing is .. it's Precise !!! That was a brilliant suggestion. I'm going to spend some time on this one

but I think that is because I used those template codes that Arpanaut put up. It certainly didn't do any harm. I'm just curious if this proceedure can be used as a "system restore" tool that when a end_user has a big prob and can get to terminal and wants to save important stuff, that he can restore his system by using the back-grade process you have suggested.

I think the safest thing to do BEFORE ANY attempt at recovery ( and actualy before starting to try U+1 ) is to back up your /home and any other important files to some form of OFFLINE storage like a usb stick or drive or cd/dvd . I learned that the hard way when feisty formated all 4 drives on my box .

to have a good offline B/U should be the first sticky on U+1 .

You should back up your information that you need and reinstall Precise from scratch

Downgrading is near impossible given issues with reverse compatibilities in packages after upgrading. It will save time and effort.

CharlesA
April 30th, 2012, 04:27 PM
backup your personal data and the do a fresh installation of Precise.

Less hassle and since the start of this thread you could have been back up and running in precise ;)

Also it is less likely to cause issues.

Peace

This.


There is. Backup whatever you want, and then take your yy.mm.iso and then do a fresh install. There is nothing else as easy and simple as that.

And this.


Thanks for everyone's input, it's just that a bunch of applications won't install or won't work because i'm in 12.10, I guess i'll just stay in QQ.

It would be easier to just see what packages are installed on the current version and reinstall them after reinstalling PP.

Just use dpkg --get-selections > somefile to get a list of packages installed and:

dpkg --set-selections < somefile to set those same packages to be installed.

@ventrical

since you are experimenting here you might want to reverse this process
http://ubuntuforums.org/showpost.php?p=11877873&postcount=38

and see if it restores synaptics behavior, as it seemed to me that it uses this template in addition to sources.list as reference to sources. #This I do not know as fact.

EDIT: +1 to CharlesA et. al.
I totally agree that backup & reinstall is the most expedient method to downgrade.

Thanks ronacc.. I have 8 machines going here. 6 towers and 3 laptops... ...oh . thats 9 :) I love doing this stuff. I'm so bored.. and so when I seen Greymechs suggestion I thought I'd give it a whirl. It is working great after all the update . Just synaptic and repos not reporting. Synaptic does download stuff but won't let me into the repos.


So I am going to restore back to Quantal and see what happens.

I'm not worried about backups because this is beta testing and I do not use my stable data installs. I have tons of hdds that I just swap in & out.

I've found it handy to have /home in a separate partition, making installation of both upgrades and downgrades much easier. Note though that downgrading may mean you have some settings which could be incompatible with another system. Better still to evaluate upgrades carefully via USB before install.

@arpanaut

Heres what happened. I re-loaded the Quantal sources.list, template, etc and then got an Apport error on "software sources". It asked me to relaunch, yes and then <send a report> yes. After 10 seconds the Software Sources came back up in synaptic. :)

I plan to go back down there to Precise and then try your code , but , also I had the same error when I reverted back to Precise so I am going to try and use the 're-launch' in Apport also.

The really neat thing is that to come back up to QQ I only had to download 33MBs of files.

I may go all the way back to Maveric and then come back up. It's a lot faster than doing backups. I am in no way saying that this proceedure is "stable" but I'm have a great time :) - and we are in beta testing :)

Expect to re-install frequently...
Better get into practice on install. And install. And re-install.

Nah, almost never necessary. I ran the same install of Intrepid Alpha 2 all the way through Lucid 10.04.2.

Four full dev cycles, some very rocky, and the system was stable as heck at the end. It's just a matter of keeping things clean and addressing issues as they arise.

Synaptic will work if I put in those Quantal templates (with Precise) but it does not work properly. When I remove the template then the Software Sources will just not come up yet update/upgrade works just great from terminal.

So now I am going to try to downgrade to Maveric and the back up to Precise then Quantal.

hehehe .. Maveric did not work very well.. Most of the repos are not active. I was , however , able to successfully get back to Quantal and a good working Synaptic.

But I think there is really something to all of this back-grading theory. It may help some who have lots of data that have borked system , get them back up and with all the data too.

I think the problem here is trying to go from Gnome 3 to Gnome 2 to Gnome 3. That's painful even as a pure LTS to LTS upgrade, and rarely works for most users. Broken dependencies galore.

Lately there's been increased focus on packaging "stability" during the testing phase. I'd posted about this initiative at the beginning of 12.04 dev cycle:
http://ubuntuforums.org/showpost.php?p=11501157&postcount=19

In my case, each of those alphas evolved into betas, rc's and eventually releases... until the subsequent toolchain upload... then back to dev. ZERO re-installs (my point in posting a response @jerrylamos), just lots of updating/fixing along the way. I've never had an experience where a final Ubuntu release would "destroy the system"!

It was essentially a rolling release of development, but eventually settled out on the Lucid release due to aging hardware. I used it daily (was my work laptop) all the way till after the 2nd point-release of Lucid(about a year past Lucid release) without any issues whatsoever. Rock-solid stable that final year.

Also, of course, it would be stupid to use a constantly-in-dev install for a work machine...I dual-boot with Arch so I always have a functional system available when things get rocky in Ubuntu alpha world :)

Thats fair enough. I guess I can rephrase myself and not be so disparging towards Ubuntu. I think it was a Natty Install on an Acer Aspire 3620 and something happened during an update , lost the wireless, couldn't get it back .. I wrote something to the effect that if the wireless is not provided for or obsoleted by an upgrade then I was going elsewhere (Fedora) [which btw worked just beautiful on that laptop]. So which brings us back to the topic of downgrading to be able to restore a system that was once working really well. I have a Dell B130. I have one hdd with the alpha 2 (updated onwards to about three weeks before release and then not updated) that works just excellently. Not a glitch at all. Then I have another hdd with a full release, post beta 2, updated, sideXside with WinXP and it sort of has lost a certain type of smoothness and ambiance.. but then perhaps that is just me. I had to manually install the broadcom drivers.. but the alpha II just pulled them right up from the start.

'destroy a system' .. perhaps my statement is too harsh and un Ubuntu_like. or I'm just plain embellishing a minor problem. I should choose my words more carefully.

Well, in my experience (I've only used N,O, and P) with Ubuntu releases, major showstopper bugs like that almost always resolve. Oneiric was rather buggy, but as I updated, all of my bugs became nonexistent.

In Fedora and OpenSUSE, however, I've never been able to get any sort of wireless configuration working.

But back to the original point, I think this method of downgrading can work, but only if there are few changes. In the case of Quantal to Precise, obviously the changes are so minute that a downgrade would be pretty simple. From Precise to Oneiric, still there were not a large amount of changes compared to in some releases. I think downgrading from 12.04 to 10.04 would be pretty impossible, because of the major file type changes from gnome3 to gnome2 gtk3 to gtk2 lightdm gdm etc etc etc.

I was really into Linux Mint Debian at one point, and upon my Debian Testing upgrading all of their repos to Gnome3 and GTK3, there was a lot of mess on my system.

I am very pleased how Precise has turned out, Ubuntu in general for that matter. I'm not belly aching and I hope it doesn't sound like that. Oneiric also. Just some natty installs. This particular install that I am working from (among 9 different PCs) was originally installed with Edubuntu 11.04(natty). Now, thats the thing, Edubuntu 11.04dvd installed great but other versions of Ubuntu Straight Up Natty had some big problems .Why? I don't know. Just reporting in . Iv'e run this system through the mill .. doing everything I can to smoke it flat - but it is very resilient. In fact, all the Ubuntus are resilient and I want to explore all the different possibilities. Thats what keeps me interested.

My training tells me the same thing that any stuffed shirt IT would dispense to their customers - declare your assumptions, document your work and do frequent back-ups. But this is 2012 and when this stuffed shirt IT (me) tells a customer to back up their system then I might as well be speaking some 5,000 year old dialect of neanthradal cave code to them because perfectly good English fails it seems. I would be better off using sign language:)

I started with Hardy Heron. It was fun. :) Then other versions of Linux and back to Ubuntu. I came back to Ubuntu because I wanted to see Unity 3D and 2D succeed (and still do) [and it is]! I still do Mint on certain PCs. It is,... elegant. Ubuntu is fun and flexible. I can do things with Ubuntu that you can't do with other OSes. You can bend it, shake it, rock it, roll it, hammer it, swear at it and it still gets up in the morning ready to serve my internet needs.

So even in our questions and our critisisms, it sparks interest and inspires innovation. We are all standing on the shoulders of giants here I think.... and .. , and YOU become that giant. What you contribute makes YOU an Ubuntu Rock Star.. and then others too can be an integral part of it all.

But in the end it's just an operating system. A simple tool that's a means to an end.

And remember my friend, your playing the piano, the piano is not playing you! Thats all the difference.

I did , just for experimental purposes, re-break a system with a bad libx file and tried this process for recovery and it did not work. The file had to be manually downgraded even after the downgrade from Quantal to Presice.

So still much more work in progress for a streamlined system restore tool for noobs :)

Well said Vertical

Even the proof readers and the documentarians deserve a star on there foreheads.Generally speaking, I am not sure how many times I have taken all that work for granted in the past.

Graham, your a genius !!

Only prob is:

ventrical@ventrical1ME051:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu quantal (development branch)
Release: 12.10
Codename: quantal
ventrical@ventrical1ME051:~$

and Quantal still comes up hard coded in System Monitor.. thing is .. it's Precise !!! That was a brilliant suggestion. I'm going to spend some time on this one

but I think that is because I used those template codes that Arpanaut put up. It certainly didn't do any harm. I'm just curious if this proceedure can be used as a "system restore" tool that when a end_user has a big prob and can get to terminal and wants to save important stuff, that he can restore his system by using the back-grade process you have suggested.

Huh. I tried the exact same thing tonight. My video card has issues in Precise... I thought I'd see if they were better in Quantal... turns out the card doesn't work at *all* in Quantal or on a 3.5.0 kernel!

Anyway, at the end my lsb_release says it's 12.04 again.

I wonder if there's a way to optimize this more -- I downgraded everything to precise -- then I had to re-upgrade in order to apply all of the precise-security updates. The security updates were >400MB. If I had preferred precise-security, then fell back on precise, that would have been a huge savings.

@postmaxin

Are you saying that one of my crazy suggestions actually works? You are joking me. Yes? Well I never. May be I will get up the nerve to test this myself. Once I recover from all the Quantal breakage that has been going on the last few days.

Regards.
