Even if I delete all the files in the ~/home/.minecraft/ folder and start the "Minecraft.jar" to recreate and download all files fresh the 1.14.4 version of the game is not working, and effectively I can no longer play Minecraft due to the server I'm playing on refusing the 1.14.3 client as too old.
By deleting all files in the ~/home/.minecraft/ folder I also delete the launcher.jar & launcher.pack.lzma files, who get redownloaded to I assume the latest version, I do this by running the pre launcher jar file Minecraft.jar wich checks if there is a launcher in ~/home/.minecraft/ and downloads it fresh, I would assume this is the latest launcher not ?
You are correct it is not the same launcher as they have changed stuff around, as the wiki talks about "19w38b" and my launcher apparently is "1.6.89-j'
Still it's weird, as everything was working fine until 1.14.4 came out, also installing the latest Minecraft.deb didn't seem to change anything in the "~/home/.minecraft/" folder, and I was left guessing after the install what happened to the files/install without explanation other then that it should install in the same "~/home/.minecraft/" folder as before, maybe the instalation folder also has changed and I'm looking for the files in the wrong directory ?
Okay I have reinstalled the latest Minecraft.deb, and this time searched for the new Minecraft-launcher and now it indeed works, some new files seem to be in "/opt/minecraft-launcher/" where the new launcher is starting from, weirdly enough it seems to get also stuff from "~/home/.minecraft/" as it recognized my user name, but my favorite servers have been removed , mmmm annoying, but at least I got it working again, thanks for the tips.
Edit: I pressed single player, the saved servers are still there
