 Summary of the bug:
 Adding ffmpeg4 and ffmpeg5 ppa causes next system update to remove
 numerous core programs,which if permitted totally hose the OS.

 This is a little odd, so some background first:

 Initially I had this problem: https://trac.ffmpeg.org/ticket/10114
 (Audio would lag behind video), and ended up adding the PPA as per
 instructions on various sites.
 sudo add-apt-repository ppa:savoury1/ffmpeg4
 sudo add-apt-repository ppa:savoury1/ffmpeg5
 This worked fine on primary and secondary PCs until a few days ago while
 doing a fresh Kubuntu 22.04 install on 2nd PC. Discover notified me that
 it was about to remove a bunch of core components as an upgrade.
 https://forum.kde.org/viewtopic.php?f=15&t=177523
 Fully expecting it to hose the OS, I allowed it. It hosed the OS.
 Using primary PC now.
 After removing all 3rd party PPA I found that ppa:savory/ffmpeg4/5 were
 the trigger.

 So now I have at least two problems:

 1) cannot use PPA 4/5 otherwise subsequent OS updates will hose the OS.

 It booted to login, but couldn't even get to a TTY, much less log in.

 2) Cannot reinstall ffmpeg from repo:
 apt search ffmpeg|grep '^ffmpeg/'
 ffmpeg/jammy-updates,jammy-security 7:4.4.2-0ubuntu0.22.04.1 amd64

 sudo apt install ffmpeg

 Building dependency tree... Done

 Some packages could not be installed. This may mean that you have
 requested an impossible situation or if you are using the unstable
 distribution that some required packages have not yet been created
 or been moved out of Incoming.
 The following information may help to resolve the situation:

 The following packages have unmet dependencies:
  ffmpeg : Depends: libavcodec58 (= 7:4.4.2-0ubuntu0.22.04.1)
           Depends: libavdevice58 (= 7:4.4.2-0ubuntu0.22.04.1) but
