Applies to: Desktop Processing Software, Ubuntu 18.04 system

Problem description

While updating on-premise Desktop Processing Software, you might see such errors pop up in the Software Updater or in the Ubuntu terminal:

E: Could not get lock /var/lib/dpkg/lock-frontend - open (11: Resource temporarily unavailable)

E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), is another process using it?


Possible Cause: Parallel operations occurring

There are, most likely, multiple software updater processes running in parallel.

Possible Fix

Check in your system if there's another software updater running in parallel or in the background. The graphic user interface of the Software Updater application might be running and causing the issue. Or, one of the following commands sudo apt-get update or sudo apt-get dist-upgrade might be running in another terminal. Make sure all of the running processes have either finished or stopped. Then, close all updating processes and start only one updater from scratch. If the issue still persists, please reboot your system and run the Software Updater application. The issue should be resolved.
