I recently had an issue with my automatic updates. The update manager was unable to do a full "security update" and as such, only a partial update was attempted. However, it appears that this has caused the UM to get stuck in an endless loop.
Obviously, re-booting the machine would break the loop but, I wanted to run this issue by the Ubuntu Forum before I re-booted the computer and tried the update again.
I suspect that the reason for these errors are because Update Manager is currently stuck in some kind of a loop and therefore using the process necessary for the attempt.
I ran sudo apt-get update from the Terminal and the following is the result:
E: Could not get lock /var/lib/apt/lists/lock - open (11: Resource temporarily unavailable)
E: Unable to lock directory /var/lib/apt/lists/
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?
This is a screenshot of the current progress; this has been going on now for more than 24 hours.

Any help is greatly appreciated.
