Hi thomas, thanks for taking the time to file a bug!

I think you may have accidentally removed a symlink from /etc/init.d:

mysql stop/waiting
invoke-rc.d: unknown initscript, /etc/init.d/mysql not found.

This symlink is needed for compatibility with things that still use the direct path to the init.d script to stop/start/etc.

You can restore it with

ln -s /lib/init/upstart-job /etc/init.d/mysql

Please try that and then run

sudo dpkg --configure -a

To complete your package installation.

If the problem persists, please report back here the results of the dpkg --configure -a command. For now, I'll close this as Invalid, but feel free to re-open it as New.
