PPA: two channels (stable, beta) instead of one?

My Ubuntu 14.04 LTS server just updated SABnzbd to "sabnzbdplus:all 1.1.0~beta1a-0ubuntu1~jcfp1~trusty", thanks to the PPA setting. So that is a beta version on my server.
I love beta's (on my laptop for example), but sometimes I prefer the recent stable versions (on a stable server).
So my preferred setup:
SAB 1.0.3 on my 14.04 Server
SAB 1.1.0 beta on my laptop.
Is there a way I can achieve that with PPA?
If not, would a "stable channel" and a "beta channel" PPA solve it, and would it be feasible? A bit like
http://www.ubuntuupdates.org/ppa/google_chrome
Code: Select all
Date Package Version
2016-06-09 22:08:06 UTC google-chrome-unstable 53.0.2763.0-1
2016-06-08 18:07:55 UTC google-chrome-beta 52.0.2743.33-1
2016-06-06 19:07:48 UTC google-chrome-stable 51.0.2704.84-1
.

From my end, the only way to do this would be two seperate ppas. As a user, you could probably get away with apt pinning.
Try something like this, in some file in /etc/apt/preferences.d/:
Code: Select all
Package: sabnzbdplus
#Pin: origin ppa.launchpad.net
Pin: origin lp-ppa-jcfp
Pin: version /~alpha|~beta|~rc/
Pin-Priority: -1
This should set prio to -1 (= don't install) for the sab package from the ppa, if the version matches the given expression (i.e. any non-final release). See
man apt_preferences for the details.
Result:
Your only issue with pinning would be the starting time of right now, given that there's a beta on the ppa and thus the only package considered for install is the one from the "slightly behind" standard repo.

OK, that solution would be great.
Result so far:
Code: Select all
$ apt-cache policy sabnzbdplus
sabnzbdplus:
Installed: 1.0.3-0ubuntu1~jcfp1~trusty
Candidate: 1.1.0~beta1a-0ubuntu1~jcfp1~trusty
Version table:
1.1.0~beta1a-0ubuntu1~jcfp1~trusty 0
500 http://ppa.launchpad.net/jcfp/ppa/ubuntu/ trusty/main amd64 Packages
*** 1.0.3-0ubuntu1~jcfp1~trusty 0
100 /var/lib/dpkg/status
0.7.16-1ubuntu1 0
500 http://nl.archive.ubuntu.com/ubuntu/ trusty/multiverse amd64 Packages
N: Ignoring file 'ppa-sabnzbd-stable-only-please.txt' in directory '/etc/apt/preferences.d/' as it has an invalid filename extension
Ouch ... that last line is not good. So I removed the extension. Result:
Code: Select all
$ apt-cache policy sabnzbdplus
sabnzbdplus:
Installed: 1.0.3-0ubuntu1~jcfp1~trusty
Candidate: 1.0.3-0ubuntu1~jcfp1~trusty
Package pin: 1.1.0~beta1a-0ubuntu1~jcfp1~trusty
Version table:
1.1.0~beta1a-0ubuntu1~jcfp1~trusty -1
500 http://ppa.launchpad.net/jcfp/ppa/ubuntu/ trusty/main amd64 Packages
*** 1.0.3-0ubuntu1~jcfp1~trusty -1
100 /var/lib/dpkg/status
0.7.16-1ubuntu1 -1
500 http://nl.archive.ubuntu.com/ubuntu/ trusty/multiverse amd64 Packages
Is this correct? I can't find documentation to verify ...
https://wiki.debian.org/AptPreferences says "apt-cache policy package gives information about the selection process. Unfortunately, it is not widely known what the output means. " ...

It looks weird, as if all priorities are set to -1? Maybe changes between trusty and xenial... I dunno.
Anyway.
https://launchpad.net/~jcfp/+archive/ubuntu/nobetas is born. I trust there'll be plenty of guinea pigs left on the original

I replaced the plain ppa setting with "nobetas", ran update/upgrade/etc, and:
Code: Select all
$ apt-cache policy sabnzbdplus
sabnzbdplus:
Installed: 1.0.3-0ubuntu1~jcfp1~trusty
Candidate: 1.0.3-0ubuntu1~jcfp1~trusty
Version table:
*** 1.0.3-0ubuntu1~jcfp1~trusty 0
500 http://ppa.launchpad.net/jcfp/nobetas/ubuntu/ trusty/main amd64 Packages
100 /var/lib/dpkg/status
0.7.16-1ubuntu1 0
500 http://nl.archive.ubuntu.com/ubuntu/ trusty/multiverse amd64 Packages
and
Code: Select all
$ sabnzbdplus --version
sabnzbdplus-1.0.3
... seems to work!
Cool! Thank you!

Is this something we should put on the new Wiki?
Seems like a good thing to have a stable and beta branch

Yes.
Instead of
Code: Select all
sudo add-apt-repository ppa:jcfp/ppa
just
Code: Select all
sudo add-apt-repository ppa:jcfp/nobetas
I could change it on the Wiki
http://wiki.sabnzbd.org/install-ubuntu-repo, but it says "The following part is (c) 2008 by JCF Ploemen", and thus I don't know if I'm allowed to add anything (IANAL).

Please don't change the Wiki, I just finished the monstrous process of transferring all wiki pages to the new wiki. We can make the changes there

I'll soon update the forum threads detailing the use of the ppa on ubuntu and debian to include the nobetas option. Info should obviously go on the wiki too someday (or simply linked from there to the relevant forum threads).

FYI, the wiki has the wrong string for the repo (
https://sabnzbd.org/wiki/installation/i ... buntu-repo):
Code: Select all
sudo add-apt-repository ppa:jcfp/nobeta
and it looks like it should be
Code: Select all
sudo add-apt-repository ppa:jcfp/nobetas
