Comment 3 for bug 1881328

Thanks for taking the time to report this bug and try to make Ubuntu better.

Checking the logs I noticed those errors:

As the message says you have multiple files associated to the same tablespace ID which makes the startup process fail. If you are trying to move those files to other directories you might want to take a look at this upstream documentation:

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".
