When I tried to install a package on an Ubuntu Linux system with
apt-getyesterday, I saw the error message below:
$ sudo apt-get install ibmonitor E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable) E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?
I saw there was another installation in progress via the Update Manager, but the Update Manager update had been running for many days without successfully completing. I couldn't cancel or kill the Update Manager update through the graphical user interface (GUI) for the Update Manager, so I checked for any process identifier (PID) associated with update-manager.
$ ps -ef | grep -i update-manager | grep -v grep jdoe 4339 1 0 2015 ? 00:02:24 /usr/bin/python /usr/bin/update-manager --no-focus-on-map jdoe 14331 1 0 Apr17 ? 00:01:21 /usr/bin/python /usr/lib/update-manager/check-new-release-gtk jdoe 25428 1 0 May01 ? 00:00:39 /usr/bin/python /usr/lib/update-manager/check-new-release-gtk
I killed all three of the processes I found associated with "update-manager", but that still did not allow me to successfully run apt-get.
