On Ubuntu 20.04 this problem also recently appeared for me. These 4
erroneous lines were at the end of the /etc/cups/cupsd.conf file, after
a closing </Policy>" line:
JobPrivateAccess default
JobPrivateValues default
SubscriptionPrivateAccess default
SubscriptionPrivateValues default
Deleting these 4 lines fixed the problem. I do not know how long they
have been there. Since both of the remaining <Policy> sections already
contained those 4 directive, I reasoned that deleting these erroneous 4
lines would be harmless. It works for me now. The cups parsing check
no longer reports a syntax error:
# cupsd -t
"/etc/cups/cups-files.conf" is OK.
"/etc/cups/cupsd.conf" is OK.
Restarting and checking the status now works fine:
# systemctl restart cups
