3 years ago This access is provided by the camera interface. Please ensure it's connected - you can check with snap connections fakecam. Ideally you should not be building yourself if you are not developing the app, but should use the version from the store (the core20 branch is in the beta channel, but will be promoted once it's stabilised - install it with sudo snap install fakecam --beta).

When I compile and run the current core20 branch, I get "Permission denied: '/sys/class/video4linux/video0/name'".
/sys/class/video4linux/video0/name has read access for user/group/everyone.
I also have run "sudo snap connect fakecam:camera".
Any idea on how this can be fixed? Is snap somewhat limiting permissions here?
