unable to get exclusive lock while upgrading to 11.10

[Mia_tech]

I just ran the upgrade application to upgrade to 11.10; however, I got "unable to get exclusive lock while upgrading to 11.10." What does that mean? is this a bug or something?

Thanks

Do you have another package manager open?

Usually means that two package managers are open at the same time. Automatic update running and using apt-get.

If you don't have any other visible package software running, you can fix by either logging out and back in, or running


ps -ef | grep apt
ps-ef | grep dpkg

and killing all other currently running apt and dpkg processes, using


kill -9 process_id
