So the kid in me wanted to play Minecraft again.
java -jar ./Minecraft.jar
But when I tried running the java launcher I got this error
I had a look on Google and found that it was sovled by running
sudo update-ca-certificates -f
This is the output of that command:
A few warnings, but I tried running minecraft again
Though still the same errors from Java as before.
I tried doing reinstalls of openjdk, ca-certificates-java and ca-certificates but this didn't change anything.
Here is the sysinfo from pacman, btw
