We are sorry that we do not always have the capacity to review 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.

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

Do you still see a problem related to the one that you reported when using a currently supported version of Ubuntu? Please let us know if you do, giving full details of the problem that you are seeing, otherwise this report can be left to expire in approximately 60 days time.

Thank you for helping make Ubuntu better.
