I upgraded an older Ubuntu computer to 20.04. Everything went well. But now the kids are telling me they cannot connect to their favourite minetest servers. The game complains about
Protocol version mismatch. Server supports protocol versions between 24 and 32. We support protocol versions between version 37 and 39.
Looking it up, I see that minetest had a big change when it went from v0.4 to v5, and newer versions are not backwards compatible.
So I found a PPA that has both older and newer versions of minetest: https://launchpad.net/~minetestdevs/+archive/ubuntu/stable
Of interest to me, it has this file: minetest_0.4.16-ppa5~ubuntu17.04.1_amd64.deb (7.2 MiB)
But...how do I install that version? I added the PPA and tried variations of this:
> sudo apt-get install minetest=0.4.16
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Version '0.4.16' for 'minetest' was not found
If I leave out the version number I do see it install the latest version from that PPA. But is there a way to force it to install an older version?
