Comment 2 for bug 29786

the bug has to due with a permissions issue for /var/run/mysqld. by default it is being set to drwxrwx---, which does not allow a "normal" user access. This being said, it only holds until the next reboot at which time it will then be reset. workaround is to either change the permissions everytime a reboot is done, or add a line to /usr/share/mysql/debian-start right after the 'source /usr/share...' to say 'chmod a+x /var/run/mysqld/'. (Thanks to cmoad on the ubuntuforms for the workaround).
