Can't entirely remove old 5.14 version of Lutris

Support

While trying to pin down why 80% of the games i tried to play on Lutris wouldn’t work, i fould out there were two different versions of Lutris installed. This i could see with the command apt list -a lutris.
The two versions installed were 5.14 and 5.22. I thought maybe it has something to do with Linux Mint’s repository only having 5.14 as the most recent update, and myself later wanting to have the latest version. I may have isntalled 5.22 through a .deb installation file.
Anyway, i tried to uninstall the old version with apt remove lutris=0.5.14-2 and later purge with apt purge lutris=0.5.14-2 so remaining files would be removed. But the two of these commands acted upon 5.22 instead !! So i lost the latest version installed and the configuration files installed.
In hopes an old version would still be better than not any working game at all, i installed 5.14 through apt again. And… it did work ! At least Trine 2 which wouldn’t work with the previous install worked this time. And checking again with apt list -a lutris it does seem this was Mint repository’s version that i wasn’t able to remove, as it’s now the only one listed.

So this topic comes with 2 questions:

  1. Could two different versions of Lutris compete with each other and prevent me from launching games ? was i right in my diagnostic ?
  2. Why was this old version of Lutris impossible to remove ? What should i do to remove it in the future, if i want a more recent version of Lutris ?

I can provide the requested logs asked about in the pinned topic in Support if requested, i didn’t have the time to produce them at the time of posting.

Thanks in advance !

I’m on a similar system (linux mint latest version), and I also have the latest version of lutris installed via a .deb. However, when I do apt list -a lutris, it shows both versions, but only the correct (later) version is installed. I presume that a) the reason for this is because since it is the latest repository version, apt will list it alongside what you have installed should they not be the same and b) that you did have the [installed] tag next to both? Incidentally, my lutris works fine, so if yours had the tag on both and didn’t work it’s plausible that that’s the reason why.
See image for my output of apt list -a lutris:

As for why the old version was impossible to remove, that would have to have been a bug with apt. It’s not supposed to let you install two versions of the same package afaik.
