pop-upgrade hangs at 100% CPU on NVIDIA channel check #400

Description

@Jachimo

The pop-upgrade process runs periodically and seemingly each time it does, it gets stuck at 100% CPU until I manually kill it. This has been going on for a while, but I just got around to trying to dig into why it's happening.

It appears that it has something to do with the NVIDIA components?

I found two similar issues:

This might be a duplicate of #327, but I'm not sure.

I've attached logs. The hang seems to have begun at July 31 2026 at 12:29:37, with this line (see journal-logs.txt):

Jul 31 12:29:37 HOSTNAME pop-upgrade[376869]: [INFO ] release_api.rs:63: checking for build 22.04 in channel nvidia

It turned my computer into a space heater for a few hours, until I killed it at August 01 2026 at 15:50:41.
