Thank you for reporting this bug to Ubuntu. We are sorry that we do not always have the capacity to look at all reported bugs in a timely manner. You reported this bug some time ago and there have been many changes in Ubuntu since that time. Your problem may have been fixed with some of the updates.

Ubuntu 16.04 (xenial) reached end-of-life on April 29, 2021.

Due to the time that has elapsed since your initial bug report I'm changing the status to 'Incomplete'.

If this issue is still present in a currently supported release of Ubuntu then please add a comment here telling us which new version it is in and change the bug status to 'New' and add a full description of the problem that you are seeing.

See this document for currently supported Ubuntu releases:
