Thank you for taking the time to file a bug report. I see the following errors in one of the files attached to this bug (DpkgTerminalLog.txt):
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! This is indeed a fatal error: the mysql process is trying to read files inside a non-existent /etc/mysql/conf.d/ directory. Maybe you have unintentionally deleted it? I would suggest purging and reinstalling MySQL from scratch, but this is most likely not a but in the software. 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".
