I have gnome-tweak-tool install and use it regulary. I cannot however install the gnome-shell-extensions-user-theme to change the shell.

I already have the ppa but when it put

sudo apt-get install gnome-shell-extensions-user-theme

into the terminal i get this output.

dvorak@dvorak-g51vx:~$ sudo apt-get install gnome-shell-extensions-user-theme

[sudo] password for dvorak:

Some packages could not be installed. This may mean that you have requested an

impossible situation or if you are using the unstable distribution that some

required packages have not yet been created or been moved out of Incoming.



The following information may help to resolve the situation:



The following packages have unmet dependencies:

gnome-shell-extensions-user-theme : Depends: gnome-shell-extensions-common

but it is not going to be installed



E: Unable to correct problems, you have held broken packages.

Can anyone elaborate on what I am doing wrong? I have tried to both install and remove both the unmet dependencies with the same error.
