Using apt-mancoosi to install Mew
I wanted to install mew today. To do so, I first tried using apt-get (Version: 0.7.25.3), and it proposes me a solution with the following characteristics:
1 upgraded, 11 newly installed, 4 to remove and 368 not upgraded.
You can find the full solution, as well as the data to reproduce this upgrade scenario online at the Mancoosi Debian DUDF repository.
I was not satisfied, because mew is just a set of emacs files, so I do not see why I should change a lot of other packages just to get them.
Then I tried aptitude (Version: 0.6.2.1-2), which proposes a solution with these characteristics:
0 packages upgraded, 2 newly installed, 170 to remove and 345 not upgraded.
Here too, you can find the full solution, as well as the data to reproduce this upgrade scenario online at the Mancoosi Debian DUDF repository.
Since this solution was not good either (in particular, it wants to autoremove a lot of stuff, and I do not have time to see whether really all of the 170 packages to remove are needed or not), I resorted to apt-mancoosi (see the Mancoosi software page) which gave me a solution, which I finally liked better
new: 2 removed: 0 replaced: 0 upgraded: 0 downgraded: 0 unsatisfied recommends:: 79 changed: 2 uptodate: 2674 notuptodate: 373
apt-get -s install mew-bin=1:6.3-2 mew=1:6.3-2
You can see just above the apt-get line generated by apt-mancoosi for implement this solution, but calling apt-get this way is not guaranteed to give the expected result: apt-get tries to recompute another solution first, and in this case apt-get, even with this command line, insists in removing stuff, so I resorted to manually downloading and installing these two packages.
We need to find a way to have apt-get or aptitude or some other package manager to apply a solution, when it is complete, like in this case.
For reference, the relevant part of the trace is copied below
