Package: aptitude
Version: 0.4.11.11-1+b2
Severity: normal
Hi,
if a new version of package foo introduces a Breaks: foo (<< 1.2), but
only older versions of foo are available, aptitude full-upgrade will
suggest to downgrade foo and bar instead of keeping the current version:
% apt-cache show libdatetime-locale-perl | grep -e
% '^Version:\|^Breaks:\|^$'
Version: 1:0.45-1+ab1
Breaks: libdatetime-format-strptime-perl (<< 1.2000)
Version: 1:0.44-1
Version: 1:0.35-1+1.5.0
% apt-cache show libdatetime-format-strptime-perl | grep -e '^Version:'
Version: 1.1000-1
Version: 1.0702-2
% dpkg -l libdatetime-locale-perl | grep ii
ii libdatetime-locale-perl 1:0.44-1 [...]

I think aptitude should prefer to keep the currently installed version
over downgrading (at least when calling aptitude full-upgrade), even
when this means no action at all will be taken.

Ansgar
PS: I'm not sure if this is the same issue as #338386 so I reported a
seperate bug.

Hi,
2009-01-15 04:49 Daniel Burrows:
On Thu, Jan 15, 2009 at 06:24:21AM +0800, [email protected] was heard to say:
I am little worried that maybe your reply was meant for a different
bug. All I know is that I am just the lowest of users using a command
line (never using the curses part of aptitude) and never have looked
at the source code.
No problem. I was just trying to say that this is a deliberate design
decision due to past feedback, but there are even better ways to do it
that I have planned out and that avoid the problem you ran into. The
rest was technical details for my own consumption when I take a look at
this bug again. (or for anyone else interested in working on it)
I think that this has been fixed for many years, full-upgrade is happy
to not do anything:
# aptitude full-upgrade
No packages will be installed, upgraded, or removed.
0 packages upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
Need to get 0 B of archives. After unpacking 0 B will be used.
As for the merged bugs:
- #574928 about Aptitude::ProblemResolver::Discard-Null-Solution=false,
should be the default now (or equivalent, so it seems to be the same
problem as the merged bug. if there's still some issue, please reopen
(and unmerge)
- #511366 is also probably the same underlying problems because
downgrades are usually not preferred over keeping current versions,
but if there's still a problem please reopen (and unmerge)
Cheers.
