I am running a Debian system which has to stay at Stretch for now and I want to install an icinga2 as client. As it should/has to be the same version as the master I wanted to use stretch-backports. Unfortunately I’m not able to do this as apt exits with an error:
$ apt install icinga2 -t stretch-backports Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: icinga2 : Depends: icinga2-bin (= 2.6.0-2+deb9u1) but it is not going to be installed Depends: icinga2-common (= 2.6.0-2+deb9u1) but 2.10.3-2~bpo9+1 is to be installed E: Unable to correct problems, you have held broken packages.
These are my sources:
$ cat /etc/apt/sources.list deb http://ftp.debian.org/debian stretch main contrib non-free deb http://ftp.debian.org/debian/ stretch-updates main contrib non-free deb http://security.debian.org/ stretch/updates main contrib non-free deb http://apt.osmc.tv stretch main deb http://ftp.debian.org/debian stretch-backports main contrib non-free
What am I doing wrong?
