[Bug 1821415] Re: pkexec fails in a non-graphical environment

[Brian Murray]

** Description changed:

- The plymouth apport source package hooks wants to gather log files as
- the root user and apport provides a policy kit policy for collecting
- that information. This works fine in a graphical environment but not in
- a non-graphical one.

- N.B. you first need to create a /var/log/plymouth-debug.log file for the
- plymouth apport package hook to actually trigger this.

- ubuntu at disco:~$ ubuntu-bug plymouth
+ [Test Case]
+ 1) ssh into an Ubuntu Desktop install of Ubuntu 20.04 LTS or Ubuntu 20.10
+ 2) sudo touch /var/log/plymouth-debug.log
+ 3) ubuntu at disco:~$ ubuntu-bug plymouth
