How to try Munin 2.1.x easily in Debian-derivatives
In my previous post I explained how to setup a simple development environment, but I feel that's a little too much if you only want to try that new, shiny, munin version.
So, let's assume that you're on a debian-derivative distribution (Ubuntu, Raspbian, ... , and of course Debian).
The nicest news is that 2.1.x already hit the experimental part of Debian. That makes it very easy to use as everything is described there.
I'll just copy/paste some instructions tailored for munin, please refer to the original page if you'd like to learn more.
Add experimental to your sources.list
echo "deb http://ftp.debian.org/debian experimental main" >> /etc/apt/sources.list
Update the apt database
Install the experimental version of munin
apt-get -t experimental install munin
Pin the munin as the experimental version
That works quite well, but the munin package won't be updated, as the automatic upgrades only comes from the non-experimental part. And obviously the version there is lower than the experimental one.
So, that is called package pinning, that is to pin a certain package in a certain repository. It is still very simple to do :
cat >> /etc/apt/preferences <<EOF Package: munin Pin: release a=experimental Pin-Priority: 800 EOF
So, that's it. You have successfully upgraded to the unstable side of munin...
