Package system still running

[SigurdF]

Hi,
my friend still runs kubuntu 12.04 long term version. Even for this version sometimes are updates coming in. The latest updates she is unable to download and install. The error message tells her that the package system still is running by another application. How can i terminate the package system that it will run with Software Update or Apper again? I tried to solve the problem with "sudo dpgk --configure -a". But it looks like that it does not work. So, what can I do?
Kind regards, Sigurd

Try:

sudo killall -9 apt-get

Then run the update.

ps -efl | egrep 'apt|dpkg' should list any running package programs

If this doesn't help, you should check if there is a lock file in one of the directories Muon accesses.


Look for /var/lib/dpkg/lock and /var/cache/apt/archives/lock and delete them if they are there.
