Hi Kenneth!
Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately, we cannot work on this bug because your description didn't include enough information. 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.

We have instructions on debugging some types of problems at http://wiki.ubuntu.com/DebuggingProcedures.

At a minimum, we need:
1. The specific steps or actions you took that caused you to encounter the problem.
2. The behavior you expected.
3. The behavior you actually encountered (in as much detail as possible).
Thanks!

Based on the version string in the title (1:10.3.17+maria~cosmic) you have installed MariaDB from upstream mariadb.org repositories, and now you are upgrading to the official version in Debian/Ubuntu.

Such an upgrade path is not guaranteed to work. Please disable 3rd party repositories (from Ubuntu point of view) and uninstall MariaDB, then proceed to install mariadb-10.3 from Ubuntu.
