 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
 ffmpeg/jammy 7:5.1.2-0ubuntu1~22.04.sav4 amd64

 sudo apt install ffmpeg
