I have installed Ioquake3 and Quake 3 launcher from the software manager and I have put the pak0.pk3 in baseq3, but I get this from the launcher:
“Required data files are missing.
Please use game-data-packager to build and install the data packages for Quake 3 Arena.
Typical use of game-data-packager:
game-data-packager -i quake3 [PATH [PATH…]]
Install game data for Quake 3 Arena, searching PATH for data files
game-data-packager -d ~/Downloads quake3 [PATH [PATH…]]
Generate game data packages in ~/Downloads to install later…”
What am I missing?
