Ubuntu
update-manager package

update manager doesn't work anymore after update python3

Asked by Stefaan Brisaert

Yesterday evening I ran an update. Apparently the python3-update-manager got updated. However, since today I get an error message when I started the update manager within Unity. A report was sent as proposed. Running an update from within the terminal seems to work normally. Uninstalling and re-installing from the ubuntu software centre didn't solve the problem. I tried throughout synaptic where I removed all related packages (3) and re-installed them after a restart..but in vain so far.

I'm quite new to linux and ran out of ideas. Anybody ?

If you run:

sudo apt-get update; sudo apt-get upgrade; sudo apt-get dist-upgrade

Does it upgrade ok?

update and upgrade from within the terminal do work fine.
I meanwhile also tried e2fsck -C0 -p -f -v /dev/sdd1, running from a live-cd, but there seem no errors in the file system.

If you open a terminal (ctr-alt-t) and issue the command

sudo update-manager

do you see an error message? If yes, please copy/paste all output into a new message of this question thread

issue the command

sudo apt-get install --reinstall python3-distupgrade

and then try

sudo update-manager

again. If there is again an error message, please copy/paste all output as done before.

I felt annoyed not finding a solution past weekend, so I reinstalled ubuntu 12.10. Already after I installed this release problems kept popping up. Never, for the past two year I used a ubuntu release causing this much problems. With this new install, I'll give 12.10 a new chance. If in the days to come, problems start again, I'll kick it of my computer and return back to 11.10 or 12.04.
Thanks for your assistance anyway.
