Ubuntu – Partial upgrade error

11.10update-manager

this is an issue I have googled a lot and I have tried a lot of fixes, but non of them really worked.

At some point (I can't remember when/how) my Update system sort of broke, and since then it is always complaining about "Not all updates can be installed, run a Partial Upgrade".

enter image description here

If I click on Partial Upgrade, I get the following result

enter image description here

But running apt-get install -f does not fix anything, and at the end I always get the following message

enter image description here

Funny thing is that my apt-get system works perfect on Console. I can update my system through apt-get update, apt-get upgrade etc..

So.. how can I fix the graphic interface? I understand that my apt-get system is not broken, but somehow its GUI it is.

Any thoughts about it?

THANKS!

P.D: I have already tried sudo dpkg --configure -a and sudo apt-get autoremove

Edit: This is the output I get after sudo apt-get update && sudo apt-get upgrade

Best Answer

Review your software sources, and remove any unused or outdated repositories.

Try one (or more) of these:

(remove unmet dependencies)
sudo apt-get -f install

(remove .deb archives from packages no longer installed)
sudo apt-get autoclean

(clear files from Aptitude cache: /var/cache/apt/archives )
sudo apt-get clean

Post the output of an update & upgrade:

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

UPDATED:

Your active sources should (most likely) not include the 'backport' elements:

This is from my setup: (edited to 'GB', instead 'NZ')

(snip)
## Uncomment the following two lines to add software from the 'backports'
## repository.
## N.B. software from this repository may not have been tested as
## extensively as that contained in the main release, although it includes
## newer versions of some applications which may provide useful features.
## Also, please note that software in backports WILL NOT receive any review
## or updates from the Ubuntu security team.
# deb http://gb.archive.ubuntu.com/ubuntu/ maverick-backports main restricted universe multiverse
# deb-src http://gb.archive.ubuntu.com/ubuntu/ maverick-backports main restricted universe multiverse

Whereas your 'sources' appear to be: (or equiv.)

deb http://gb.archive.ubuntu.com/ubuntu/ oneiric-backports main restricted universe multiverse

These should also NOT say 'oneiric-backports' !?
