[Bug 1590892] Re: package util-linux 2.27.1-6ubuntu3.1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1

[Neil Rotherham]

I eventually got the updates to install by removing the WICID and WIFI Radar network scanners one of which I *think* was employing the runmbbservice (because the "mmb" bit seems to stand for "mobile broadband") Then I ran "sudo apt update && sudo apt upgrade" which then gave the following errors:
insserv: warning: script 'K01unlockgcstartup' missing LSB tags and overrides
insserv: warning: script 'K01gcstartup' missing LSB tags and overrides
insserv: warning: script 'S02lockgcstartup' missing LSB tags and overrides
insserv: warning: script 'lockgcstartup' missing LSB tags and overrides
insserv: warning: script 'gcstartup' missing LSB tags and overrid es
insserv: warning: script 'unlockgcstartup' missing LSB tags and overrides

I then ran "sudo dpkg --audit"
Which tipped me off to add empty LSP tags (after #!/bin/sh) to the latter three (the first three were links in a different directory to the second three) like this:

### BEGIN INIT INFO
# Provides :
# Required-Start :
# Required-Stop :
# Default-Start :
# Default-Stop  :
# Short-Description : Some info
# Description :       Some more info
### END INIT INFO

Then I ran "sudo dpkg --configure -a" which still seemed to complain
they were missing, but this time the "sudo dpkg --audit" command
returned nothing. Repeating "sudo apt update && sudo apt upgrade"
succeeded this time. Since I'm still not entirely sure what I have
managed to do, I think I've been very lucky. The moral of the story, I
think, is to be careful downloading free software even if it's through
the System Tools->software menu item.
