Please describe your issue in as much detail as possible:

Sometimes when my Steam client updates in gamescope-session, or when the bootstrap resets itself from within gamescope-session, the update will hang on:

[2025-05-21 15:21:27] [2025-05-21 15:21:27] Extracting package...
[2025-05-21 15:22:38] [2025-05-21 15:22:38] Installing update...

for 10+ minutes:

with no activity in my steam logs if I watch the directory. If I steamos-session-select plasma and let the Steam client boot up there, the entire update process only takes 30 seconds at most.

In my logs, the period I was stuck on that screen was between 15:21:27 and ~15:34:00 before I gave up and switched to desktop via ssh. At this point, you can see the Steam client completes the update and runtime configuration via the Desktop client in ~45 seconds.

Steps for reproducing this issue:

1. Trigger a bootstrap reset from within Game Mode (this is the most consistent hang)
   or
2. Trigger a normal Steam client update from within Game Mode (this is a bit less common)
