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

Ser etter ny utgave av Ubuntu

Traceback (most recent call last):

  File "/usr/bin/do-release-upgrade", line 144, in <module>

    fetcher = get_fetcher(options.frontend, m.new_dist, options.data_dir)

  File "/usr/bin/do-release-upgrade", line 37, in get_fetcher

    from DistUpgrade.DistUpgradeFetcherCore import DistUpgradeFetcherCore

  File "/usr/lib/python3/dist-packages/DistUpgrade/DistUpgradeFetcherCore.py",       line  30, in <module>

   import tempfile

EOFError: EOF read where not expected

Error in sys.excepthook:

Original exception was:

Traceback (most recent call last):

 File "/usr/bin/do-release-upgrade", line 144, in <module>

 fetcher = get_fetcher(options.frontend, m.new_dist, options.data_dir)

 import tempfile

EOFError: EOF read where not expected

axept@aXept-Lifebook:~$

And when running apt-cache info:

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

ubuntu-release-upgrader-core:

Installert: 1:0.190.7

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?

This install is NOT new, my laptop has been running fine for months without problems.

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.

UPDATE: Get the same error when trying to add a repository from terminal.. Whats going on??????

UPDATE 2: When "Update Manager" launch automatic with new system updates, it doesn't work. Nothing happens when I click "Install now" button..
