View Full Version : [all variants] What would be a reasonable approach towards release updates?

Hi, tried to look for a comprehensive answer but without success...

Background: about a year ago I started to use Linux again after almost 7 years of break. Used to use Debian Sid + XFCE so Xubuntu was a natural choice. I am very happy with the overall experience and totally enjoy my "back to old times" experience...

BUT

Recently I did my second release upgrade and it was a second time in a row when it blew my system up the way I had to spend couple of hours brining it back to some usable state. Actually after last upgrade I still strongly consider reinstalling the whole thing completely. Smells like Windows ;-)

Question: what could I do to prevent/minimize such events? Wait 2 months before upgrading? I already did wait 2-3 weeks and was not rushing to upgrade straight after release but still run into trouble. Some different approach? I'd probably like much more some kind of a gradual upgrade process. With the all-at-once approach it's much harder to find suspects after a crash. Is such "gradual" procedure available? I know this might sound like a stupid question, but still decided to ask it. :-)

Thank you in advance for all helpful answers!

One of the top culprits in failed upgrades to new releases is the failure to first remove proprietary drivers. Have you been doing that.

Stick with 14.04 LTS and don't release-upgrade until April 2019

+1 to both of the above but adding

Keep the user interface in a default state or revert it back to the default sate if heavily modified & remove any applications that were downloaded from the web and not part of what Ubuntu Software Centre offers.

Did you upgrade to 15.10, and is your machine using an AMD graphics system and the fglrx driver?

That has been a major problem for upgraders, even though it was a known bug and mentioned in the release notes for 15.10. You can either look at the work-arounds for this, which I can't find at this moment, or temporarily remove fglrx with
sudo apt-get remove fglrx* until the problem is fixed.

I'll keep looking for the details of the workaround for you, and will come back with the info.

Found it.

The work-around for some has been to enable the proposed repositories and install fglrx only from them, then disable proposed again.

See https://bugs.launchpad.net/ubuntu/+source/fglrx-installer/+bug/1493888 for the bug and details.

Thanks for your suggestions.

So it is quite as I was afraid - I have not missed any silver bullet solution and the only somewhat-reasonable option is sticking to the LTS versions (thanks tgalati4
).

The "no proprietary drivers" rule was known to me and it was not a problem. I had quite a few others e.g. (Just to give examples! I'm good, the intention of this thread was finding some general solution, not detailed troubleshooting):

- upstart to systemd switch for some, still unknown to me reasons results in a spectacular failure during boot
- random system hangs (after Werewolf)
- my desktop PC won't turn off after entering halt command, need to use power switch again

So if nobody else has my silver bullet - you can close the thread. I'll strongly consider using LTS :/
