Hi,
I'm trying to get CPDB installed on trixie, and I think I found a
dependency problem, which I *think* is a bug (or maybe I don't understand the
architecture)
From the source for libcupsfilters, I see this statement
> ... the original cups-filters package got split into 5 separate packages:
libcupsfilters, libppd, cups-filters, braille-printer-app, and cups-browsed,
with libcupsfilters and braille-printer-app not containing PD file support code
any more and cups-browsed being planned to drop explicit use of PPD files.

So per that, libcupsfilters2 replaces cups-filters, per https://github.com/
OpenPrinting/cpdb-backend-cups CUPS, v2.2 is a dependency of cpdb-backend-cups
libcupsfilters2 does not replace cups-filters. It does not work with
cups-filters 1.x. To use cups-filters with libcupsfilters2, cups-filters 2.x is
required.
So therefore, I should be able to do install cpdb-backend-cups... which I guess
installs libcupsfilter2 as a dependency and libcupsfilter2-common replaces cups-
filters (and has both Breaks and Replaces cups-filters for it's dependencies)?
According to apt, that means cpdb-backend-cups is completely incompatible with
cups.
the cups-filters which needs to get installed is 2.x, cups-filters 1.x needs to
be removed or updated to 2.x. Then you can (must) have libcupsfilters2 and then
you can install cpdb-backend-cups.
I do not think libcupsfilters2-common is working as intended here. Either the
dependency information for libcupsfilters2-common is wrong (and it should
satisfy the dependency of cups-filters for anything that needs it), or cups
should be made to work with libcupsfilter2-common. Or am I misunderstanding
something, and somehow cpdb-backend-cups is intended to replace cups (in that
case, someone needs to rebuild gnome because gnome-core is dependent on cups)
If the installation of libcupsfilters2 as a dependency of cpdb-backend-cups does
not make cups-filters 1.x updated to cups-filters 2.x, there is a bug in the
dependency definitions in the *.deb packages.
