Do you have a bug reference for this behavior in apt (preferably with a
reproducer case)?
This reminded me of this older bug from Karmic-Lucid era, which I'm
not sure ever got fixed since we just worked around it in
update-manager:
https://bugs.launchpad.net/ubuntu/+source/apt/+bug/571999
Ok. Does that mean there's no bug filed for the case of apt looking at
recommends on the wrong version of the package?
Yes, I was misremembering the exact circumstances of the linked bug.
In this case apt is looking at a stale cache package rather than the
to-be-installed package.
That's not an accurate characterization of what's happening here. The error
message shown in the log is from dpkg, not from apt:
Selecting previously deselected package wine1.2.
dpkg: regarding .../wine1.2_1.1.42-0ubuntu4_amd64.deb containing wine1.2:
wine1.2 conflicts with wine (<< 1.2)
wine (version 1.1.42-0ubuntu4) is present and unpacked but not configured.
So in fact, it's dpkg that's detecting phantom conflicts with
previously-installed versions of packages that have since been removed.
I've updated the bug report accordingly.
Thanks
I suspect that bug has since been fixed, as I haven't heard anything about
this kind of failure recently.
It was a pretty rare edge case then, so I wouldn't necessarily count on
it just because it hasn't cropped back up.
