[SOLVED] Error when installing additional software (LL 2.2)

[sysdrum]

Have you tried open terminal and running

Code:

sudo apt-get autoremove

and see if the system removes any odd unused decencies that my be hanging up the system in the update.
If not I know you probably already tried this but try just running

Code:

sudo apt-get update

without an upgrade if that goes through but the system is still not doing what is soppose to try

Code:

sudo apt-get install -f

there could be a broken install in the mix that should correct it, or atleast let you know if something else is going on.
