I tried to replicate this by installing the cups snap as per Call for testing: OpenPrinting's CUPS Snap but there doesn’t seem to be a /var/snap/cups/common/run/cups.sock:

amurray@sec-hirsute-amd64:~$ sudo systemctl stop cups-browsed
amurray@sec-hirsute-amd64:~$ sudo systemctl disable cups-browsed
amurray@sec-hirsute-amd64:~$ sudo systemctl stop cups
amurray@sec-hirsute-amd64:~$ sudo systemctl disable cups
amurray@sec-hirsute-amd64:~$ sudo snap install --edge cups
amurray@sec-hirsute-amd64:~$ snap info cups

ls: cannot access '/var/snap/cups/common/run/cups.sock': No such file or directory

So then it is not surprising that the cups-admin-test snap cannot access it :slight_smile: - is there something else I need to do for the cups snap to create this socket?
