Help! I broke the Software Manager in Mint

Hi there! Is anyone up for a challenge to help me fix broken Software manager
(I had a go on Mint forum, but no one could help)
Linux Mint 20.1 Cinnamon, 5.4.0-91-generic kernel
Issue:
in Software manager, some (most) of the software appears with Install button greyed out saying "not available".
Examples of "unavailable: VLC, Audacity, Smplayer etc
But for example Spotify and Inkscape are available (I was able to install Inkscape as a test )
Gimp's flatpak instance is available, but not the ususal one
Strange, maybe related issue:I noticed that GIMP disappeared from the list of software in the menu, although its files are still there. I went to reinstall it (that's when I noticed that it was "unavailable" in Manager - But its flatpak version was available, which I installed since)
Attempted fix:
In Software Sources Gui, reverted to default morros, disabled all PPA and additional Repos. Did not make a difference. (Now enabled all back and switched to local mirror again)
Possible causes
- maybe (but only maybe) this happened after I installed youtube-gl and its front end; but I am not certain it is related, and if the issue was already there. I ran these commands:
Code:sudo apt install python3-pip ffmpeg
sudo pip3 install youtube-dl
sudo pip3 install --upgrade youtube-dl
sudo echo "deb http://www.deb-multimedia.org buster main non-free" > /etc/apt/sources.list.d/multimedia.list
sudo apt update -oAcquire::AllowInsecureRepositories=true
sudo apt install deb-multimedia-keyring
sudo apt install youtube-dl ffmpegThe installation worked, but I do recall some error message
I had to give my user permission to access /etc/apt/sources.list.d/ at some stage becasue of "access denied" message; but I have changed the permissions back to default since then
I got it all from https://www.lifewire.com/download-yo...eos-p2-2202105
I reinstalled the Manager in Synaptic, and got this:

All packages are up to date.I am on local mirror in software sources, because the default one I noticed was not available (it seems)
