[Thegrayjedi]

So after running the script, everything is downloading and installing just fine until this section:

Any ideas? I really need to get this installed so I can mod Fallout4. Thanks!

nevermind, it was an issue with protontricks being the wrong version - @Thegrayjedi

on Ubuntu 22.04 the version of protontricks you get via apt is 1.7. If you follow their install guide to use flatpak then it worked for me.

https://github.com/Matoking/protontricks

[Thegrayjedi]

I'll try that when I can, thanks @largereptile

[DominicWatson]

@largereptile @Thegrayjedi I'd recommend NOT going with the Flatpak version. This caused issues for me that meant various problems in MO2 due to permissions.

Instead, the only thing that worked for me is installing using pipx. You get the latest version + no file permissioning issues. YMMV.

So install pipx, e.g. apt install pipx if using debian/ubuntu based. Then:

pipx install protontricks

[largereptile]

Fair dos, I just reconfigured the permissions for flatpak - I think they've got alright instructions for it on the protontricks github

[Thegrayjedi]

Flatpak version worked for me just fine. True, MO2 spits out errors like nobody's business, but they seem to be text or display related errors. AKA, nothing new in WINE.

In short, if anyone is having issues installing MO2 that matches the "Magic Number" error, it is the ProtonTricks version mismatch, you need 1.10.1.

That error should be renamed, but meh. We figured it out.
