Sup, so, I'm not familiar with linux at all so help is much appreciated. I've been trying to boot my pc up from a live CD unsuccessfully. I get to the stage at which there are the options to test without installing or install or so on where I select 'Install Ubuntu.' Here it relays through some fast DOS commands until it reaches 'end trace' and then, eventually, 'Killed.'

I have already got a functional 11.10 version installed, could this be a problem? The reason I am attempting a reinstall is because the package system is damaged inside 11.10, a problem I can't seem to solve. If I try to install any new software from within the software centre it tells me that two banshee extensions must be removed. I try to remove these from inside the terminal, using apt-get remove, which results in:**

You might want to run apt-get -f install to correct these:

The following packages have unmet dependencies.
 banshee-extension-ubuntuonemusicstore : Depends: banshee (>= 2.2.1) but 2.2.0-1ubuntu2 is to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

The software centre suggests that I disable all third party repositories and run apt-get install -f I have done so but the package system remains damaged and apt-get install -fattempts to install banshee 2.2.1 but returns:

Errors were encountered while processing:
 /var/cache/apt/archives/banshee_2.2.1-1ubuntu3_i386.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)

I have also tried apt-get update (runs fine) and apt-get upgrade. The upgrade command apt-get upgrade results in:

Reading package lists... Done
Building dependency tree

You might want to run ‘apt-get -f install’ to correct these.
The following packages have unmet dependencies.
 banshee-extension-soundmenu : Depends: banshee (>= 2.2.1) but 2.2.0-1ubuntu2 is installed
 banshee-extension-ubuntuonemusicstore : Depends: banshee (>= 2.2.1) but 2.2.0-1ubuntu2 is installed
E: Unmet dependencies. Try using -f.

I seem to be going round and round in circles here! If only I could reinstall successfully.

Only proposed updates (oneiric proposed) is not enabled.
