12.04 stuck in Partial Upgrade

[daniellog]

When I run update manager in 12.04, it wants to do a partial upgrade for some reason. When I commit it I get the following "Can't guess meta-package error"...

If I remove ubuntu-desktop then try again I get an error with it trying to remove unity when its on a blacklist, looks like it might be trying to remove a lot of packages on my system :S

It reads like you have removed some key desktop dependencies. Are you receiving only recommended updates ?

[daniellog]

Yes I am, any way I can fix these dependencies?

[Frogs Hair]

You can try the following command but I don't understand the part about unity and blacklist.

sudo apt-get install --reinstall ubuntu-desktop

I managed to do some upgrades, but after those it went back to wanting to do a partial upgrade with the same error :(

Seems like
sudo dpkg --configure -a and
sudo apt-get -f install are the magical commands.

Run
sudo apt-get update after you run those two commands.

Tried the commands and when I launch update manager it still wants to do a partial update, here's a screenshot of what it wants to install...

Review your software sources, and remove any unused or outdated repositories.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

UPDATE:

sudo apt-get install aptitude

and then run


sudo aptitude

UPDATE 2 :
Or Install Synaptic if you don't have it and in the edit menu run "Fix broken packages" . If that doesn't work I'm out of ideas.

Best of luck.

Seem to have found the problem, our work repo was trying to push some squeeze packages to my box, once disabled the problem has gone. Thanks for your help! :)
