Mint 20 cinnamon 64 bit here:
rx 580 8GB sapphire nitro+ video card
The update manager keeps showing Mesa 20.2~git2008051930.24b80~oibaf~f is ready to intall
I install it and upon reboot or even later upon checking for new updates ( regardless of the amount of time or if I manually click Refresh to do so) it keeps showing that same update is ready for downloading and installing as if My system forgot it has already done this.
glxinfo | grep “OpenGL version” yields " string: 4.6 (Compatibility Profile) Mesa 20.2.0-devel (git-65d23e7 2020-08-04 focal-oibaf-ppa) " ( without quotes obviously)
So it would appear 20.2 IS installed. All my games work perfectly ( warcraft III battle chest retail original two disc set is a different story)
What am I missing or doing wrong here? Please help
