Comment 6 for bug 1508441

Possible regression. I have vagrant -> puppet setting up ubuntu 14.04 from scratch on a semi-regular basis. After the package was released I see this:

==> one: Setting up mysql-server-core-5.6 (5.6.27-0ubuntu0.14.04.1) ...
==> one: Setting up mysql-server-5.6 (5.6.27-0ubuntu0.14.04.1) ...
==> one: start: Job failed to start
==> one: invoke-rc.d: initscript mysql, action "start" failed.
==> one: dpkg: error processing package mysql-server-5.6 (--configure):
==> one: subprocess installed post-installation script returned error exit status 1

After I SSH into the box and run it manually:

# /etc/init.d/mysql start
 * Starting MySQL database server mysqld
No directory, logging in with HOME=/
-su: 31: source: not found
   ...done.
 * Checking for tables which need an upgrade, are corrupt or were
not closed cleanly.

Then mysql server runs correctly.

More info:

# apt-cache policy mysql-server-5.6
