insserv: Starting ezproxy depends on plymouth and therefore on system facility `$all’ which can not be true!

Had a new installation of EzProxy that was working fine until I updated nginx.

Somewhere in the upgrade process, while dpkg was trying to set up nginx and/or open-iscsi, the following errors started

insserv: warning: script 'K00ezproxy' missing LSB tags and overrides
insserv: warning: script 'ezproxy' missing LSB tags and overrides

[Solved] Edit /etc/init.d/ezproxy to include (after the #!/bin/sh line):

### BEGIN INIT INFO
# Provides: ezproxy
# Required-Start: $local_fs $network
# Required-Stop: $local_fs
# Default-Start: 2 3 4 5
# Default-Stop: 0 1 6
# Short-Description: ezproxy
# Description: EzProxy Server
### END INIT INFO

Go back and run “dpkg –configure {package}” for the erroring installs.
