Unable to get exclusive lock
I am no longer able to install anything from limewire to Miro. In the add/remove applications, I get
"Unable to get an exclusive lock
This usually means that another package management application (like apt-get or aptitude) is already running. Please close that application first."
I have tried restarting, killing other applications like update manager, but every command leads to:
E: could not get lock /var/lib/dpkg/lock - open (11 resource temporarily unavailable)
E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?
