apt-get, 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.
$ kill -9 4339 $ 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? $ ps -ef | grep -i update-manager | grep -v grep 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 $ kill -9 14331 $ kill -9 25428 $ ps -ef | grep -i update-manager | grep -v grep $ sudo apt-get install ibmonitor E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable)
I then checked to be sure there was no other instance of apt-get running, but saw none.
$ ps aux | grep apt-get | grep -v grep $
Since I had killed the processes I found associated with "update-manager"
with kill -9, I figured there as a lock file remaining, since
I had terminated the processes abnormally. When I checked for the presence
of a lock file in /var/lib/dpkg, I found there was
one there.
$ ls /var/lib/dpkg/lock /var/lib/dpkg/lock
After I removed the lock file, I was still unable to successfully run apt-get.
$ sudo apt-get install ibmonitor E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem. $
I then ran the sudo dpkg --configure -a command as suggested in
the error message.

I was then able to successfully run the apt-get command, though
in this case the package I was attempting to install didn't exist; I didn't
think the ibmonitor package was already available, but I wanted to use
apt-get to verify that was the case. I saw that there was no
existing package available for the utility.
