[Sergio Durigan Junior (sergiodj)]

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

From the logs attached to this bug:

ERROR: Unable to start MySQL server:
mysqld: Can't read dir of '/etc/mysql/conf.d/' (OS errno 2 - No such file or directory)
mysqld: [ERROR] Stopped processing the 'includedir' directive in file /etc/mysql/my.cnf at line 20.
mysqld: [ERROR] Fatal error in defaults handling. Program aborted!

It seems like the /etc/mysql/conf.d/ directory might have been manually removed before attempting to install the MySQL package. Could you confirm if that was indeed the case, please?

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".
