Upgrade from 12.10 to 13.04 fails and apt problem

[axept]

When trying to upgrade my release from 12.10 to 13.04 I get this output in terminal:



axept@aXept-Lifebook:~$ sudo do-release-upgrade

And when running apt-cache info:


axept@aXept-Lifebook:~$ apt-cache policy ubuntu-release-upgrader-core
ubuntu-release-upgrader-core:

And:



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

Don't do anything. All is up to date apparently..

Trying to launch "Update Manager" gives the same error as "do-release-upgrade". Tried to remove .pyc files in /etc/apt/dist-packages/ and reinstalled python stuff as found in a Bug-report...


Any suggestion?


Btw, running "Software packages" from "system-settings" doesn't work. It won't start. Suppose its the same reason.. Its been slow to start before, but now it just won't start.



I also get this error when trying to add a repository from terminal.. Whats going on??????

[dino99]

open /etc/apt/sources.list, and change "quantal" by "raring", and deactivate third party repos if any, like ppa(s)
save and close that file, then update/upgrade again

note: think to clean the system before doing the above commands: clean/autoclean/autoremove/gtkorphan/bleachbit

[axept]

And where should I disable third party repos when I can't open the GUI, what file?

You can do it in file /etc/apt/sources.list

You edit this file as root:
gksudo gedit /etc/apt/sources.list
and write a # sign before the line referring to the ppa you want to disable

[axept]

There's no third party PPA's in there, like steampowered, private launchpad etc..

[axept]

Up you go..

No one that have a clue why I can't add PPA's or even start Update Manager? When System shows there's updates for my system I can't install them, because the install button doesn't work..

axept; Hi !

Sources may be located in
/etc/apt/sources.list
or
the directory /etc/apt/sources.list.d/

ls -la /etc/apt/sources.list.d/
more likely the PPAs' source is in that directory.



just try'n to help

Thanks,

Tried many things last night with live help. Seemed to be a corrupt *pyc file somewhere. Whatever I did, I got the same error. So this morning I gave up and installed a fresh install of 13.04..
