Hi!
During the upgrade from PS 5.6 to PS 5.7 (Percona repos) I’ve found problem with standard apparmor profile of Ubuntu 14.04.
To make PS 5.7 work, I had to add these lines in /etc/apparmor.d/usr.sbin.mysqld:
/var/run/mysqld/mysqld.sock.lock rw,
/run/mysqld/mysqld.sock.lock rw,
Without it, PS just cannot start.
Is it possible to include these changes in deb package by default?
