protontricks seems to lack permissions, running as sudo results in crash (returncode: 69)

[sebastianrueckerai]

Describe the bug

I am following this guide to get Gothic II to run:https://bfloeser.de/posts/gothic/#the-absolute-minimum
Installing the needed components via protontricks results in errors.

To Reproduce

1. Install protontricks on Ubuntu via pipx
2. try protontricks 39510 directmusic

Expected behavior
should install directmusic

System (please complete the following information):

• Distro: Ubuntu 22.04.4 LTS
• Protontricks installation method: pipx
• Protontricks version: 1.11.1
• Steam: Latest Beta

Additional context

If I do protontricks 39510 directmusic I get:

Any help would be appreciated!

Protontricks creates a set of Wine wrapper scripts under $XDG_CACHE_HOME/protontricks/<Proton name>/bin/; $XDG_CACHE_HOME is usually $HOME/.cache. If this directory doesn't have execute permissions (eg. because the mount has noexec set), that could explain the permission problem.

The location has caused problems before. I might set it to prefer $XDG_RUNTIME_DIR instead if that's available, as it might have better guarantee of having execute permission.

@Matoking thanks! Anything I can do in the meantime to make it work on my end?
Also, if this is a permission problem, why is "sudo -E protontricks " not working either, do you know?

[Matoking]

Don't run Protontricks as root! It's generally a bad idea for general applications, as even if it does work it can make a mess of your file permissions. Protontricks does not require administrator rights.

I've pushed an experimental fix described above to the check_mount_noexec branch. Since you're using pipx, could you install it using the following command and check if it solves your issue?

$ pipx install --force git+https://github.com/Matoking/protontricks.git@check_mount_noexec

If that doesn't solve the issue, could you try running mount and posting the output here?

@Matoking I tried your new version, unfortunately it did not work:
