[BUG] Installation says is "requires superuser access to finish setup", but doesn't ask for it, then displays an error that installation "is incomplete."

[jMyles]

So far I've installed Steam from both Snap and Flatpak and had the same outcome:

It displays a dialog box, saying "SteamVR requires superuser access to finish setup. Proceed?" The available options are "No" and "Yes."

Clicking Yes causes the dialogue to disappear, but it does not then go through the normal flow of asking for superuser access.

Subsequently, a dialogue box ("error" severity) appears, saying: "SteamVR setup is incomplete, some features might be missing. See Steam client logs folder for details."

A cursory look through the logs doesn't show me anything that immediately stands out, but there are quite a lot of logged messages and I'm not sure what to grep for.

After the error message, SteamVR launches, but my headset (Bigscreen Beyond) is not detected.

To Reproduce Steps to reproduce the behavior:

1. Install SteamVR
2. Click "Yes"
3. See error

Expected behavior For the installation to proceed normally.

Update:

I presume that ~/snap/steam/common/.local/share/Steam/steamapps/common/SteamVR/bin/vrsetup.sh is the shell script being run under the hood here.

If i run this command manually, it produces a dialogue with a different style (appears to be steam-styled, rather than OS default), again saying that it needs sudo to finish setup. This time, however, it does actually ask.

I give it the requested permission, and indeed the subsequent error goes away. However, it still doesn't detect my Bigscreen Beyond.
