On the Minecraft Download Page
https://minecraft.net/en-us/download/wever,
For linux, the instructions are to download the .DEB, and then perform:
apt-get install Minecraft.deb
However, this is incorrect. It should be:
dpkg -i Minecraft.deb
then
apt-get install -f
to force install of dependencies...
Thanks!
