Ok, I think I ran into the same bug upgrading yesterday from 10.10 to 15.04.
I was able continue by doing three steps: 1. Adding the mysql Repos(may not be necessary) https://dev.mysql.com/downloads/repo/ 2. Tried doing apt-get install mysql-server and got this error: "Setting up mysql-community-server (5.6.26-1ubuntu15.04) ... mysqld: Can't read dir of '/etc/mysql/mysql.conf.d/' (Errcode: 13 - Permission denied)" 3. Removed apparmor apt-get remove apparmor apparmor-utils 4. Did apt-get install mysql-server -> This time it worked! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/305107 Title: mysql refuses to start because missing !includedir configuration directory To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mysql-dfsg-5.1/+bug/305107/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
