View Full Version : [kubuntu] Unable to get exclusive lock

November 16th, 2008, 10:45 PM
I have a problem with this lock thing. I am using ubuntu 8.4 with KDE. When I want to upgrade to 8.10 using Adept Manager it says following:

Unable to get exclusive lock
This usually means that another package management application (like apt-get or aptitude) already running. Please close that application first.

There's no apt-get or aptitude running.
When trying to do it with aptitude or apt-get it says it could not get lock. I found the 'lock' but I don't know what to do with it. It's only an empty document.

The lock file is supposed to be deleted when the application using it is closed, it is OK to delete the lock file.

I tryed to delete it but I couldn't. Not even as root. Is it possible that some aplication running as deamon is using it? How do I find what application then??

I solved my problem :) It was Adept Manager itself creating the lock and then it wanted it again. Well I tried to rm the lock as a root after launching the application and it worked out.
Jim, thank you for the advice about the lock.
