Hello, this is my first post, so let me know if I need to adjust anything.
I got an error trying to use the Web Installer on Debian Sid: Failed to execute 'claimInterface' on 'USBDevice': Unable to claim interface.
I found this related post: https://discuss.grapheneos.org/d/8881-web-install-process-fail-unable-to-claim-interface
Which noted someone had to disable fwupd. My version is well above the version that the WebInstaller notes needs to be stopped:
inam@home:~/gamedev/essay$ apt-cache policy fwupd
fwupd:
Installed: 2.0.6-4
Candidate: 2.0.8-2
Version table:
2.0.8-2 500
500 http://deb.debian.org/debian sid/main amd64 Packages
*** 2.0.6-4 100
100 /var/lib/dpkg/status
But it still didn't work until I disabled it. I don't know if the WebInstaller source code is Open Source, but if it is, I would be happy to add code to at least throw an error to the console/page suggesting to disable fwupd if navigator.platform is Linux. Again, not trying to overstep, just want to help. I can try to reproduce as needed.
