Bug#1084021: regression in 2.4.2-3+deb12u8: client hangs retrieving printer information
Package: cups
Version: 2.4.2-3+deb12u8
Severity: serious
X-Debbugs-Cc: team@security.debian.org
My setup:
- headless host A running cups 2.4.2-3+deb12u8, with printer connected
via USB, makes the printer available to host B
- host B running cups 2.4.2-3+deb12u7, printing from evince. Works like
a charm.
Then I:
- upgrade cups on host B to 2.4.2-3+deb12u8
- restart evince, press CTRL+P, select the printer by clicking on it
once in the printing dialog
- this hangs displaying a (localized) message that I think might be
something like "Retrieving printer information..." in the original.
I tried other combination of versions. It seems 2.4.2-3+deb12u8 on host
B is what breaks things.
I'm more than happy to provide information on the configuration, just
please let me know what to provide, printing remains a black magic to me
:-(
FWIW the printer looks the same in GNOME printer settings dialog on host
B whether it works for evince or not - the printer address is "(null)"
in both cases.
