Status changed to 'Confirmed' because the bug affects multiple users.

From your Log:
 mysql-client-5.7 conflicts with virtual-mysql-client
  "Mariadb-client-10.0" provides "virtual-mysql-client" and is present as "unpacked but not configured".

Mariadb and Mysql are mutually exclusive.
This usually is handled by package dependencies and conflicts, but I can't see how you got into this situation.
I'd recommend trying to purge and traces or mariadb and then re-install all mysql components.
That should resolve the issue for you.

Thank you for taking the time to file a bug report.

It looks like you had mariadb installed at one point. Mariadb and
installing mysql from ubuntu will conflict. To get passed this you
need to remove all the mariadb packages first, and then attempt to
install mysql again.

Since it seems likely to me that this is a local configuration problem,
rather than a bug in Ubuntu, I am marking this bug as 'Incomplete'.

However, if you believe that this is really a bug in Ubuntu, then we
would be grateful if you would provide a more complete description of
the problem with steps to reproduce, 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".
