Comment 7 for bug 1206648

We have the same problem in 5.6.14-rel62.0-483.precise. In our environment, the mysql-common package is already installed and then we install percona-server-server-5.6 which depends on percona-server-common-5.6 which forces mysql-common to be removed and /etc/mysql along with it. The server then fails to start with the same error as reported above.

  $ dpkg --contents percona-server-common-5.5_5.5.34-rel32.0-591.precise_amd64.deb
