22.04 LTS upgrade two days ago from a fully-upgraded and maintained original 18.04.2 install from ISO in 2019.
During upgrade I did receive several warning popups; can't recall the text now because I clicked "report" and the upgrade continued. The warnings were pretty generic.
At any attempt to run any video, or even just start Totem, fails with "Totem could not startup (sic). Some necessary plugins are missing. Make sure that the program is correctly installed."
VLC Media Player doesn't even get that far: simply nothing happens.
This lead down several deep rabbit holes: 1) which plugins are missing? 2) where are they in the file system? 3) what source would provide those plugins; etc etc
Ended up removing and reinstalling Totem. No joy. That led down another rabbit hole where I ended up with
sudo apt install ./totem-plugins_42.0-1ubuntu1_amd64.deb
in an attempt to install missing plugins; still no joy.
Want to post this w/out reading other similar posts because they seem to refer to Totem installs that do work to some degree, or wander off into Window Media Player or something.
How can a plain-jane 22.04 LTS upgrade to a fully-maintained, original Ubuntu 18.04.2 ISO install get b0rked so badly?
It has been fully upgraded and maintained by Ubuntu's own maintenance/upgrade cycle, per Ubuntu's maintenance notifications. Not sure how this translates into "non-standard upgrades and hacks".
No hacks were used anywhere, at any time, in the maintenance cycle of the original ISO install.

"sudo apt update" "All packages are up to date." "sudo apt install totem-plugins" "totem-plugins is already the newest version (42.0-1ubuntu1)." "sudo apt install totem-plugins-extra" "E: Unable to locate package totem-plugins-extra"

should do it. – mchid Aug 14 '22 at 13:44ubuntu-restricted-extras
package is needed for codec support which should at least solve the vlc problem or other media player issue which you may be able to use instead of totem. Other media player suggestions: gstreamer, mvp. – mchid Aug 14 '22 at 13:50
