help
When try to run Synaptic, I get the error message," Unable to get exclusive lock," when I try to install a package with Discover I get, " unable to obtain lock."
All the checking that I have done points to another process running and interfering with what I am trying to do.
When run sudo dpkg-reconfigure -a, I am told to run, "sudo dpkg-reconfigure libdvd-pkg."
When I run that, I get, :debconf: DbDriver "config": /var/cache/debconf/config.dat is locked by another process: Resource temporarily unavailable,"

How can I correct this?
Thanks for your help

you can't run more than one instance of the installation application. In order to unlock you need to close all instances, then run the following command in a konsole:

Code: Select all

lsof /var/cache/debconf/config.dat


this should tell you the PID number of the process locking the database, You can kill it with the command

Code: Select all

kill -9 (PID number)


If you don't get any results from the lsof command this means the lock is already gone.
