What did you have installed before you upgraded into mariadb 5.5.41? Did you migrate from mysql 5.5 or from an older version of mariadb? Was the previous version installed from the official Ubuntu repositories or somewhere else?
When you were asked the migration question in the graphical UI, did you respond with 'yes' or 'no'?
Thanks @Julien!
