Does a server count?
When 12.04 came out my server was still running 11.04. I did the upgrade in two steps, first to 11.10 and then to 12.04. There where no troubles in going from 11.10 to 12.04, however there was a minor problem going from 11.04 to 11.10. For some reason 11.10 didn't replace GDM with LightDM, all it did was remove GDM. Simply installing LightDM fixed it and then, as I said, upgrading to 12.04 was a breeze.

Yes, a server counts.
I meant by saying "through update manager" that you didn't use a external CD/DVD of 12.04 or a USB . You just used the AWESOME feature of Ubuntu of upgrading through Ubuntu server(i.e update manager).

I did last week on a acer3.1 gig desktop. Ugraded to Ubuntu instead of xubuntu.So far I just had to change the desktop back. No luck with dual boot on Acer netbook though with W7 on it.

@helmut0 (http://ubuntuforums.org/member.php?u=151299) : Any problems you faced while upgrading to Ubuntu on acer3.1 gig desktop ??

Hi!, satyamM,

I upgraded to 12.04 from 11.10 with Update manager on the first day of its release, with no real problems.

The only trouble was that it upgraded to 3.2.0-23-generic, which was still the Beta, and after completion there were 372 updates needed to bring it up to 3.2.0-25.

So it took a long time, and required many interactive responses, so it could not be left to get on with things on its own.

As compared with that, a clean install of 12.04.1 3.2.0.29-generic-pae #46 took less than 2 hours, including downloading the .iso, burning the LiveCD, formating the partition and installing; with only 9 updates needed afterwards.

Though, of course, it then still needed the re-installation of additional programs and configuration.

On the whole, if you have a lot of installed apps and a reliable Internet connection, the Update route is the best, despite reports of problems.

Chao!, bogan.

You can see bugs reported during 12.04.1 upgrade testing in the upgrade section here:

http://iso.qa.ubuntu.com/qatracker/milestones/230/builds

The only bug I encountered was this:

https://bugs.launchpad.net/ubuntu/+source/pango1.0/+bug/1038573

Something I would point out, you said:


If you have successfully upgraded to 12.04 from 11.10 or 11.04 or 10.10 or 10.04 or earlier

The only supported direct upgrade paths to Precise are 10.04 -> 12.04 and 11.10 -> 12.04, and that may NOT apply to all flavors - I only tested Ubuntu.

You should also check out the appropriate release notes:

The only way I COULD upgrade to 12.04 was through updates.

I firstly had to install - what I call - classic 10.10 and upgrade to 11.04 etc to 12.04; The reason for this was because only 10.10 was able to deal with my RAID 0 set up.

Seriously, I love Ubuntu linux and it is excellent that it is developed by people who just have a passion for it. But if I could try and persuade the developers to integrate RAID support in live desktop CDs for future releases, that would be great. Further, I think the issue is to do with UEFI motherboards too, yet 10.10 does not have a problem with them.

10.10 has, in fact, saved me a lot of times. I would go so far to say that newer releases have regressed in some aspects, which is a shame.

Still, I l'Ubuntu.

@3246251196

These upgrades, did they break your RAID set up? I ask because I understand that people use the alternate CD to install Ubuntu and configure RAID and I have heard that when 12.10 comes out there will not be any 12.10 alternate CDs.

The standard Ubuntu installer will give options to configure RAID (so I have heard) but not all the options. The full range of options will not be available until the release of 13.04.

So, it seems, to me, to be important that a person with RAID be able to upgrade from 12.04 to 12.10 without breaking the setup. I do not have RAID so I cannot experiment.

Regards.

Thanx for pointing out the mistake and for the rest info. :-)

I upgraded a laptop from 10.04 to 12.04.1 with no problems, my desktop was also upgraded the same way and it had the fgfs [flightgear] bug, but the system seems stable so far.

I would regard both these upgrades as successful.

I upgraded, more or less, one month ago from 10.04 to 12.04 my hpcompaq 6720s laptop.

The upgrading was a success and took about one hour.

The only issue was, I had installed wicd in my laptop as net manager since network-manager was unusable in 10.04 (connects and disconnects wifi all the time). In the upgrading, network-manager was installed and started. The two network managers cannot work in the system at the same time, so I had to uninstall network manager.

After trying unity and gnome shell desktops, I finally selected gnome fallbak DE wich fullfils my expectations and is light in my laptop.

The only drawback in my system since upgrading is the long time to boot (in 10.04 was abot 40 seconds). I explain, since I select in grub the kernel till the page to select DE and log in apppears is about 45 seconds, then once selected gnome fallback desktop till the computer is usable, it takes about 35 seconds more. I have asked for help in this forum but I haven't got any usefull advice or tip in order to reduce it.
