Upgrading from 20231030 to 20231031 breaks network printing via CUPS
Last modified: 2023-11-05 22:17:17 UTC
After upgrading via zypper dup to 20231031 network printing via CUPS is broken. Restarting cups and cups-browsed didn't resolve. Unclear what diagnostic information would be relevant here, but let me know and I can share additional details.
I think the root cause is some change outside of CUPS and/or cups-filters (the latter contains cups-browsed) because as of today (03.Nov.2023) nothing changed in CUPS since 20.Sep.2023 and nothing changed in cups-filters since 17.May.2023, see https://build.opensuse.org/package/view_file/openSUSE:Factory/cups/cups.changes?expand=1 and https://build.opensuse.org/package/view_file/openSUSE:Factory/cups-filters/cups-filters.changes?expand=1 To debug certain network printing issues https://en.opensuse.org/SDB:Printing_via_TCP/IP_network could be somewhat useful but it depends on what the root cause is why printing via network fails, e.g. when the reoot cause is a generic networking issue then generic networking debugging would be needed.
It seems the update resulted in some files in /etc/cups being changed (and a .ppd file being deleted). Reverting changes to those files fixed the issue. It's unclear if this was a one time issue, or if there's a regression in some of the update scripts causing, among other things, for the ppd file in /etc/cups/ppd to be deleted.
after reverting the CUPS configuration things seem to be working (as of 20231103). the root cause is still unclear, but closing this for now. will reopen if needed.
