Hi Paul and Laurent, thanks for your bug report. Can you please check what happens when you manually run tha same commands that you see as failed?
For example, from Laurent's log: sudo /usr/lib/snapd/snap-device-helper add snap_brave_brave /class/video4linux 0:0 && echo ok Also, if you don't mind, please attach the syslog when such error occurs (by the way, do they happen at every boot, or irregularly?) sudo journalctl -b I suspect that this and bug 1971955 might be related. ** Changed in: snapd (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1968878 Title: systemd-udevd: video4linux: Process '/usr/lib/snapd/snap-device-helper add ... /class/video4linux 0:0' failed with exit code 1.
