View Full Version : [ubuntu] upgrade window lost during upgrade to 12.04

I pressed alt-tab during the upgrade from 11.10 to 12.04 (using the graphical update manager tool). Now I see my background but nothing else. Everything is vanished. I don't see a taskbar, files, buttons or whatever.

When I left for work this morning my disk was still working so I left it on.

Is there a way to get back to the upgrade window(s) ? The update manager tool is probably waiting for user input.

When I get back home tonight I'll first try alt-tab again. I will also try pressing the ALT key. Would there be any other way to get back to the upgrade window if alt-tab doesnt work ?

Unity is new for me because I have always used Ubuntu 10.04 and 10.10 so I don't know which keycombinations I should try.

I am able to go to a ctrl-alt-f1 and type commands.

I would rather not do a reboot.

I found multiple people with the same problem:
http://ubuntuforums.org/showthread.php?t=2009377
http://answers.launchpad.net/ubuntu/+source/apt/+question/199964
http://askubuntu.com/questions/124829/should-i-restart-my-pc-if-unity-crashes-during-upgrade

I reported a bug on launchpad : http://bugs.launchpad.net/ubuntu/+source/unity/+bug/1107733

If I have to do a reboot what is the best strategy ? What's the best way to fix an incomplete upgrade ?

My plan if I can't get back to the upgrade window:
0: go to control+alt+f1
1: look at the logs in /var/log/dist-upgrade
2: check reported ubuntu version with : lsb_release -a
3: check /etc/apt/sources.list. use http://repogen.simplylinux.ch/index.php if needed.
4: stop (kill) the upgrade process. remove any lock files if needed.
5: finish configuring stuff with: sudo dpkg --configure -a
6: If lsb_release -a doesn't say 12.04 then do : sudo do-release-upgrade
7: if needed complete upgrade with:
sudo apt-get update
sudo apt-get -f install
sudo apt-get -f upgrade
sudo apt-get -f dist-upgrade
8: only if really needed automatically reconfigure all packages (takes a long time): sudo dpkg-reconfigure -phigh -a
9: do some cleaning up:
sudo aptitude clean
sudo apt-get clean
sudo apt-get --purge autoremove
sudo apt-get purge $(dpkg -l | awk '/^rc/ { print $2 }')
10: to make sure all packages are updated:
sudo apt-get update
sudo apt-get dist-upgrade
11: sudo reboot and hope for the best


Anything I have missed? Does Ubuntu clean anything else after a succesful release upgrade ?


Thanks!

Solved. When I got back from work I could see the upgrade window but I still couldn't interact with it. I went to control-alt-f1 and did the cleaning up phase by hand.

I continue to have problems. I couldn't work with Ubuntu after login (blank screen/automatic reboots/hangs).

Maybe it is related to my intel video chipset and/or compiz and/or unity ?

I have an intel video chipset (GMA 945?) but I can't check lshw/lspci right now for the exact information because I'm at work.

I installed gnome-panel and I switched to using the x-swat ppa.

When I try http://askubuntu.com/a/127849 I get a segmentation fault regarding icons. I also don't see most icons. And I have some other problems regarding window management and program crashes.

I suspect my problems are somehow it's related to libgdk-pixbuf2.0-0.

unity_support_test is all good.

I'm going to try sudo dpkg-reconfigure -phigh -a

I tried the following:

sudo apt-get install libgdk-pixbuf2.0-dev
sudo dpkg-reconfigure -phigh -a
sudo reboot

Then I tried the following from a gnome-classic-no-effects sesion in the terminal:

sudo su
gdk-pixbuf-query-loaders > /usr/lib/i386-linux-gnu/gdk-pixbuf-2.0/2.10.0/loaders.cache
exit
gconftool-2 --recursive-unset /apps/compiz
unity --reset
