I have just upgraded our printserver to Leap 15.3 and the cups web interface appears to hang up, often taking 20-30 seconds to load. At start-up, I see a couple of error messages in the log, but I think they're unrelated: E [31/May/2022:15:55:09 +0200] [CGI] cups-brf must be called as root E [31/May/2022:15:55:09 +0200] [cups-deviced] PID 11775 (cups-brf) stopped with status 1!
