Hello, Gnu Röoty writes: > Hi I have a problem with the CUPS service. What is the problem? Does ‘sudo herd status cups’ tells the service is not started? What about listening ports and running process?

Could you post your full system ‘config.scm’? > I upgrade my GuixSD with sudo -E guix system reconfigure /etc/config > but it's same. I run a ‘sudo -E guix system reconfigure /etc/config’ command [1] to reconfigure my system, too. Did you run ‘guix pull’ before [1] command? What does ‘guix --version’ tell? Do logs contain useful information (‘/var/log/messages’ and ‘/var/log/cups/access_log’, ‘/var/log/cups/error_log’ files)? Thanks, Oleg.
