APT Preferences for a specific package

Postby adam777 on Wed May 09, 2012 4:15 pm

Hello all,
Following this thread - http://forums.linuxmint.com/viewtopic.php?f=199&t=101565, and all the advice I received in it, I did some searching.
On the surface, it seems that the APT Preferences file is exactly what I need.
The default one reads:
Code: Select all
Package: *
Pin: release o=linuxmint
Pin-Priority: 700

Package: *
Pin: origin packages.linuxmint.com
Pin-Priority: 700

Package: *
Pin: release o=Debian
Pin-Priority: 500


and the default sources.list reads:
Code: Select all
deb http://packages.linuxmint.com/ debian main upstream import backport romeo
deb http://debian.linuxmint.com/latest testing main contrib non-free
deb http://debian.linuxmint.com/latest/security testing/updates main contrib non-free
deb http://debian.linuxmint.com/latest/multimedia testing main non-free


Now, for the sake of testing, I installed the ati driver from default repositories (version 12.2) and than tried to create a setup in which ONLY this package (fglrx-driver) is being updated from the unstable repository.
First, I added the relevant repository to source.list:
Code: Select all
deb http://ftp.debian.org/debian unstable main contrib non-free


Next, I tried setting up the relevant entry in preferences:
Code: Select all
Package: fglrx-driver
Pin: a=unstable
Pin-Priority: 991


This is where I got stuck, as aptitude upgrade tries to pull a full sid upgrade (~700 packages upgrades).

I even tried removing:
Code: Select all
Package: *
Pin: release o=Debian
Pin-Priority: 500


and adding:
Code: Select all
Package: *
Pin: a=unstable
Pin-Priority: -10


With no success.

I hope the goal is clear - to let this one packages update from unstable (along with its dependencies) while the rest remain with default repositories.
It doesn't seem reasonable that the package dependencies will result in such a massive update, so I must assume something isn't properly configured.

Thanks in advance, Adam.

* EDIT *
Just tried again, this time doing a proper sid upgrade.
There are a little more upgrades available comparing to my attempts above.
So perhaps this one package does trigger that much dependencies?

Well, it is the graphics driver for your X system; it might have one or two dependencies:

Re: APT Preferences for a specific package

Thank you both, I'll keep toying with it.
Perhaps I should have tested with a "simpler" package as a sanity check.

Re: APT Preferences for a specific package

Postby adam777 on Thu May 10, 2012 4:48 am

OK, here is the current situation.
I used the following preferences file:
Code: Select all
Package: vlc
Pin: release o=Debian,a=unstable
Pin-Priority: 900

Package: *
Pin: release o=Debian,a=unstable
Pin-Priority: 50

Package: *
Pin: release o=linuxmint
Pin-Priority: 700

Package: *
Pin: origin packages.linuxmint.com
Pin-Priority: 700

Package: *
Pin: release o=Debian
Pin-Priority: 500


Now, apt-cache policy for vlc displays the following, as expected:
Code: Select all
 vlc:
  Installed: 1:2.0.0-0.1
  Candidate: 2.0.1-4+b1
  Package pin: 2.0.1-4+b1
  Version table:
 *** 1:2.0.0-0.1 900
        500 http://debian.linuxmint.com/latest/multimedia/ testing/main amd64 Packages
        100 /var/lib/dpkg/status
     2.0.1-4+b1 900
         50 http://mirror.isoc.org.il/pub/debian/ unstable/main amd64 Packages
     2.0.0-6 900
        500 http://debian.linuxmint.com/latest/ testing/main amd64 Packages


However, once I try to launch an upgrade (even aptitude full-upgrade) operation, I get the following:
Code: Select all
No packages will be installed, upgraded, or removed.
0 packages upgraded, 0 newly installed, 0 to remove and 1 not upgraded.
Need to get 0 B of archives. After unpacking 0 B will be used.


The one "not upgraded" being vlc.
It's more than likely the upgrade cannot proceed because the newer VLC package also requires other newer packages to be obtained from unstable.
However, If I change the unstable to different priority other problems arise:
- more than 100 - gets priority over installed, but not over normal repository, and so the upgrade will still not use the needed packages from unstable.
- more than 500 - gets priority over both installed and normal repository, which will cause a full system upgrade, not what I want.

I'm aware of the fact that the whole pinning scheme is usually done with manual installation of a package stating "unstable", but is there no way of pinning to unstable not a single package (vlc) but a package along with all its dependencies?

Adam.

subscribing with interest.

this works here
Code: Select all
zerozero@debian:~$ inxi -Sr
System:    Host: debian Kernel: 3.2.0-2-amd64 x86_64 (64 bit) Desktop Gnome Distro: Debian GNU/Linux wheezy/sid
Repos:     Active apt sources in file: /etc/apt/sources.list
           deb http://ftp.debian.org/debian testing main contrib non-free
           deb http://security.debian.org/ testing/updates main contrib non-free
           deb http://www.debian-multimedia.org testing main non-free
           deb-src http://ftp.debian.org/debian testing main contrib non-free
           deb-src http://security.debian.org/ testing/updates main contrib non-free
           deb-src http://www.debian-multimedia.org testing main non-free
           deb http://ftp.debian.org/debian unstable main contrib non-free

had no preferences file, so made this one for this experiment
Code: Select all
zerozero@debian:~$ cat /etc/apt/preferences
Package: *
Pin: release a=testing
Pin-Priority: 500

Package: *
Pin: release a=unstable
Pin-Priority: 200

and the result is
Code: Select all

bare in mind a couple warnings:

Re: APT Preferences for a specific package

Postby adam777 on Thu May 10, 2012 4:36 pm

Appreciated, zerozero.
I think the main problem lies with the fact that I try to get the work flow to go exclusively via upgrades, not explicit installs.
Suppose I do make an explicit install from unstable, I can work the priorities so no downgrade will occur to VLC and its dependencies.
However, I'm back where I started - once a new version comes up in unstable, I will not get updated via the upgrade command, but have to some how learn of the new version and perform another manual install from unstable.
The above is not much different in terms of update convenience to installing from a deb file manually.

Coming to think of it, a "solution" that would work would be to generate a list of all the dependencies for all the packages I want from unstable using apt-rdepends (that is, for example - VLC and its dependencies plus fglrx-driver and its dependencies etc.).
Once I have such list, create a MASSIVE preferences file pinning each of those packages to unstable.
Theoretically that should work.

That being said, this solution is as gentle as a bull in a china shop :D
Considering this is still my trial and error period, I'm still keeping an eye for the upcoming release of Mint 13, where such things are easier to accomplish using PPA's.
Perhaps the disadvantages comparing to LMDE aren't so substantial after all...

- again, this needs further adaptation for lmde;
- needs for sure more tweaking (i'm a nOObie regarding this subject)

Hmmm, wildcards, an interesting idea :D
Will try to work it out and report back how it ended.

Re: APT Preferences for a specific package

Postby adam777 on Fri May 11, 2012 7:49 am

Well, seems like a dead end :(
The use of wildcard isn't that helpful, as VLC depends (on different level of the recursion) on about 200 packages, only 5 of which contains "vlc" in their name.
Granted, from all those 200 packages only about 10 do not meet requirements in current state (that is, most of the packages VLC depends on are installed and have a recent enough version).
While I could pin those 10 packages to make sure they are updated from sid, things are rather dynamic I suppose, and so it will not help much.
Seems like manual installation and updating, complete switch to sid or just switch to Mint 13 are the possible solutions.
Thanks again, zerozero, it has been a good lesson :D

PS. On a more general view, the fact that VLC alone depends on ~200 packages, and considering that it is only one application, really makes me doubt the usefulness on a mixed system in this situation.

Re: [~Solved] APT Preferences for a specific package

Postby zerozero on Fri May 11, 2012 8:18 am

adam,
well i can see where is the problem here, and why it doesn't work for you but it did for me in testing (even with those upgrades and downgrades)
- you are tracking latest frozen around march/20th
- i'm tracking testing (updated daily and following closely sid)
- you are jumping through 2 months worth of updates (and that probably can be done but is out of my skills)

Re: [~Solved] APT Preferences for a specific package

Postby adam777 on Fri May 11, 2012 9:16 am

I completely forgot about UP, so I have pointed my machine to use the testing repositories, and an aptitude upgrade is on the move as we speak.
Lots of updates, even while using safe-upgrade, once I'm on the other side, I'll see how it goes.

Since I kind of like the idea of UP, mainly in order to make sure all the mint stuff is functioning as it should, a thing that is more likely to break when tracking testing directly, this is mostly a kind of sanity check.
As is the situation this days, the mint repositories can get quite behind the debian ones when the team is busy preparing a release or whatever.
So I'm (in my eyes at least :D ) simulating LMDE with UP5, and see how it goes from there.

Adam.

PS. As a nice bonus, the standard debian repository has a much faster mirror for me comparing with mint servers.
PPS. Your LMDE FAQ has been of great assistance.

just a quick note: i don't use aptitude (find apt more reliable, but that's another story), anyway you might want to check if aptitude full-upgrade gives any extra output. you want to be full updated :)

tks about the faq

Re: APT Preferences for a specific package

Well, upgrade hasn't gone so smoothly - from the top of my head - the LMDE desktop background (which I suppose is part of a more comprehensive package) and the ATI control panel both went missing.
Perhaps it has something to do with the default preferences file not playing so nice with tracking testing directly.
Any idea if I should change something in the default preferences file so upgrade will behave better when tracking testing? (before even attempting any pinning or such thing).
Default reads:
- Mint packages priority - 700
- Debian packages priority - 500
Perhaps I should add something regarding "testing" priority.
At least in the case of the ATI control panel (fglrx-control), there were two dependencies in which the first solution aptitude suggested was to keep as is (thus not installing fglrx-control), while the second solution was to upgrade to a newer version sourced from testing following by the installation of fglrx-control, which is pretty much what I want it to do all the time...

adam,
coming to testing has a price see this post
about that particular issue i think it's related with this and this
i have no idea what happened to the ati control panel :oops:

edit: i missed the edit you've made to the post.

my opinion: (but it's up to the user) that once you go to testing or sid you should get rid of the preferences file this is from yesterday

OK, I'll try to begin from a fresh installation, this time using no preferences file.
On a more general note, taking a little detour and that's about it regarding the matter:
When tracking testing directly, is there any significant difference between LMDE and Debian testing, assuming all the mint stuff is still working? (and yes, it's a bit simplistic...).
