I've tried with Linux Mint 20.4 and 21.1 (Based on Ubuntu 22.04) with the same problems:

FSOInstaller installs mediaVPs and mods correctly except the second part of Freespace Open 22.2.0 Linux Standard. Error is always "FreeSpace Open 22.2.0 Linux Standard: The file 'mod.ini' could not be downloaded." I can still run the base Freespace2 from the Linux executable it downloads.

The instructions for Knossos linked at the top under the link Installing Freespace Open don't work. The PPA ngld/knossos is not compatible with newer versions of Linux, error is "Cannot add PPA: ''This PPA does not support jammy''." I've also tried building from the github source - I just get a blank window with a bar at the top saying the version number and a purple and black thing in the corner when I run ninja run, nothing else.

WXlauncher does not work either, tried building from source and installing the version available in app install with the same issues, advanced settings page just says "the executable did not generate a flag file" and play is greyed out. Mods and mediaVPs appear correctly on it and it is detecting the two downloaded linux executables though. I guess this might be related to the FSOInstaller second stage failing.

From the knossos thread:

If you don't like bash-scripts, here is how it worked here on Ubuntu 20.04

git clone https://github.com/PhantomHoover/old-knossos
cd old-knossos
pip3 install raven
pip3 install token-bucket
yarnpkg install

Tl,dr: you need to use PhantomHoovers fork on current linux systems

Okay, at first I had exactly the same issue as before. I then made an alias for python specifically to python3.10, compiled and ran it again and now it works. python3 was pointing to python3.8 before, but it wasn't giving any errors when compiling. ¯\_(ツ)_/¯

And for future reference to anyone with a similar problem in the future, the qt5-default package doesn't exist anymore and I also had to run npm install .

Thanks.

Also, can I move all the mediavps and mods I already have over or do I need to completely redownload them again through Knossos? It seems to only be detecting the retail FS2 install and not the other stuff in that directory that I downloaded using FSOInstaller.

Knossos uses another mod metadata format, as far as I know, it is easiest to re-download everything.

There is a more up-to-date knossos build available which should work with current Ubuntu versions. Grab it here: https://pxo.nottheeye.com/files/test/knossos/knossos_0.15.0-dev+73b131a_all.deb
