I get the same kind of error trying to install packages from the command
line. It appears jockey backend is holding the lock. This likely a
manifestation of bug #373795 as I'm behind a proxy, though I think
software center should be changed to report a less ominous error message
for LockFailedException. jockey-backend should be fixed to not make the
system unusable if it can't find the package sources, and preferably
also fixed to obey system proxy settings (eg bug #373795).
