I was able to reproduce this with both my desktop (Debian Testing, as reported in initial issue description) with an Index as well as SteamOS 3.5.7 and an HTC Vive. In both cases, rolling back to 1.27.5 allowed room setup to complete, and moving forwards to 2.1.7 / 2.1.8 retained the room setup configured in 1.27.5.
Nothing extracted yet.
Describe the bug

Additional context
Switching to the temp_v1.27.5 branch allows Room Setup to work again. Once room setup has run, the calibration is usable in 2.1.7 / 2.1.8.
