package courier-authlib-mysql 0.63.0-4build1 failed to install/upgrade: subprocess new pre-removal script returned error exit status 1

This worked when I retried the upgrade with mysqld running. (I had the server in maintenance mode, which meant switching off most services.)

Argh. This hit me again because I didn't remember that mysql is needed running while the upgrade runs.
Very annoying.

authmysqlrc removed (held sensitive data)

courier-authdaemond needs to be running, too.

Seems like the postinst script blindly assumes all services are running so it can take them down.
