Thank you for your report.

This looks like a local configuration problem, rather than a bug in Ubuntu. Specifically, 5.7.20-1ubuntu16.04 has never been shipped by Ubuntu, so you seem to have a problem caused by a customisation made on your system, rather than this being a bug in Ubuntu.

You can find pointers to get help for this sort of problem here: http://www.ubuntu.com/support/community

Since we use this bug tracker to track bugs in Ubuntu, rather than configuration problems, I'm marking this bug as Invalid. This helps us to focus on fixing bugs in Ubuntu.

If you believe that this is really a bug, then you may find it helpful to read "How to report bugs effectively" http://www.chiark.greenend.org.uk/~sgtatham/bugs.html. We'd be grateful if you would then provide a more complete description of the problem, explain why you believe this is a bug in Ubuntu rather than a problem specific to your system, and then change the bug status back to New.
