Using Backports in the Business Editions

Postby zerozero » 27 May 2014 01:25

Two big warnings to start:
  • Backports are not meant to be used with the Home Edition (SolydX and SolydK); Backports are only meant to be used with the Business Edition (SolydX-BE, SolydK-BE and SolydK-BO)
  • Backports are meant to be used sparsely
    It is therefore recommended to select single backported packages that fit your needs, and not use all available backports.
    there's a risk (although low) of incompatibilities when using these packages
===

What is Debian Backports
http://backports.debian.org/
Backports are packages taken from the next Debian release (called "testing"), adjusted and recompiled for usage on Debian stable. Because the package is also present in the next Debian release, you can easily upgrade your stable+backports system once the next Debian release comes out. (In a few cases, usually for security updates, backports are also created from the Debian unstable distribution.)
The Business Editions are designed to offer a rock solid environment where stability is paramount, even if that means sometimes at the cost of using older packages.
The problem is that either for hardware compatibility or new features that upstream released in the meantime some pieces of software needs to be updated to meet those demands;
Using Backports we ensure (the best we can) that the system stays reliable and stable.

===

Adding Backports to sources.list

Code: Select all

sudo echo 'deb http://ftp.us.debian.org/debian/ wheezy-backports main contrib non-free' | sudo tee -a /etc/apt/sources.list.d/backports.list

Code: Select all

sudo apt-get update
Important Adding the Backports repository and updating/upgrading or dist-upgrading won't upgrade or install packages automatically from the base system to the version available on Backports because
All backports are deactivated by default (i.e. the packages are pinned to 100 by using ButAutomaticUpgrades: yes in the Release files
Once you install (explicitly) the Backport version, you will get updates to that package (if available) as normal.

===

Installing packages from Backports

you can browse online here >> https://packages.debian.org/wheezy-back ... llpackages the available Backports

and apt policy <package> will give us also useful information regarding a given package we want to install.

then use

Code: Select all

sudo apt-get -t wheezy-backports install <package>
to actually install the required package.

Nice tutorial!

Note that you don't have to backport LibreOffice.
The backported LibreOffice is added to our own repository.

i altered the tutorial a bit:
1. removed the recommendation to use synaptic: if the package is installed and there's a new version on Backports synaptic won't see the higher version; better to use apt.

2. better explanation about what happens when you add backports to sources.list and update for the first time after that.
