I tried to install an older Minecraft version, because Optifine isnt auvailable for the newest one. When I click in New installation in the Launcher, and try to select a version, no matter which version I choose, it doesnt change the version in the selection field, it just stays on the “latest release” option.
Environment
Linux Ubuntu
Hello Luca, thanks for reporting this bug to MoJira. its actuly a pretty common one so let me see if i can help.
To provide this you can:
Update the Launcher
Run the launcher as Administrator
Clear the Launcher Settings
Create a new profile manually (Go to installations and then make a new one)
Reinstall the Launcher
This bug might be relatet to a corrupted config or a permission issue (pls chek for that)
Hope i could Help -Toucka
