Seeing a similar case today (non-PASS).
To be removed
darktable
ufraw
ufraw-gimp
Not seeing anything replacing them, but
lensfun is being upgraded (along with a large number of
libs...
Will see what it does, after a little more searching...
EDIT
Adding back
ufraw and
ufraw-gimp reports
Unchanged
liblensfun0
and appears to have processed OK.
EDIT2
Adding back
darktable reports the same "Unchanged" for
liblensfun0 again...
Appears to install OK.
Should this be a Broken Package report?
EDIT3
If I "Reload" and "Mark All Upgrades", Synaptic wants to remove
darktable,
ufraw and
ufraw-gimp again, without doing any installs or upgrades. Not going to let it, for now...
