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 14.04 (trusty) reached end-of-standard-support on April 25, 2019.

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 otherwise this report can be left to expire in approximately 60 days time.

Thank you for helping make Ubuntu better.

Hi Paul, since my post, I migrated to Ubuntu 22.04.
You can close this report.

[Paul White (paulw2u)]

Thanks for your prompt reply.
Closing as fixed in a later release.
