package xbmc-live (not installed) failed to install/upgrade: subprocess installed post-installation script returned error exit status 2

failed to install, due to error i cant remember. then i kept getting message 'an application wants to access the keyring, but the keyring is locked. please type in your password for the default keyring.
ive tried to uninstall all XMBC components, but it kept failing to carry out the actions, and recieved similair error messages. Restarted Xubuntu, and had a crash report soon after start up. Then submitted this report.
