Install on Ubuntu 20.04 - unmet dependencies: icinga2 : Depends: icinga2-bin (= 2.12.0-1.xenial)

I’m simply trying to install icinga2 on Ubuntu 20.04 server and I can’t seem to get pass this depency error.
My focal-icinga.list has
deb icinga-focal main
deb-src icinga-focal main

But I 'm getting:

sudo apt-get install -y icinga2

I’ve tried alteady installing icinga2-bin manually although I suppose I 'm not supposed to, but they springs a new set of errors.

Is this a known issue ? Should I install from another package or downgrade my Ubuntu ?

thanks for any input.

Is this a fresh install of 20.04 or did you do a upgrade from 18.04?
Are any(this) packages placed on hold? apt-mark showhold

Fresh install (nothing shows on hold)

Hi !

Can you specify what ubuntu release it is ?
Is it the Ubuntu 20.04.1 Server (64-bit) or is it the desktop version ?



Server (64) (running in VM - if that matters)

Distributor ID: Ubuntu
Description: Ubuntu 20.04.1 LTS
Release: 20.04
Codename: focal

5.4.0-48-generic #52-Ubuntu SMP Thu Sep 10 10:58:49 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

No, VM doesn’t matter. I just needed to know if it is server or desktop version. and the minor release number which you already gave. thanks for that.

I investigate why this might be happening.



thanks ! (I notice now I was a bit brief in my reply, apologies, I got distracted right before send :slightly_smiling_face:

Hi Dimitri!

As far as i have installed now the Ubuntu 20.04.1 System & Icinga 2 i’ve got no problems.

Here my short History of Steps done

    1  apt get update -y
    2  apt-get update -y
    3  apt-get upgrade -y
    4  wget -O - | apt-key add -
    5  vi /etc/apt/sources.list
    6  apt-get update -y
    7  apt-cache search nagios-plugins-all
    8  apt-cache search nagios-plugins
    9  apt install nagios-plugins-contrib -y
   10  apt install icinga2
   11  systemctl status icinga2
   12  history | less

Besides the typo with apt-get & adding the sources via “vi /etc/apt/sources.list” which is just adding the two lines at the end of the sources.list file

deb icinga-focal main
deb-src icinga-focal main

then updating via “apt-get update -y”

After that as a primary step installing the plugins with “nagios-plugins-contrib” and then installing icinga 2.

And so far no error with the dependency and the the service is running fine.

Just to be sure ? It is not an In-Distro upgrade from an older version ? And therefore the old xenial stuff is popping up ?



Thanks for all the work … i guess I 'll just delete everything and re-try.

No, I just downloaded from
Installed it, and more or less performed the steps you did… it’s so basic that I 'm puzzled to what is going wrong or different.

Maybe a hidden special character via c&p that sometimes occurs … who knows. From our side ATM all we can say it should work.

I tried now two times, no strange cache or proxy settings that i’ve found which intervene or present the wrong repository.

But please let us know if it is still occuring.



I believe I found what was wrong, my /etc/apt/sources.list still contained a reference to
deb-src icinga-xenial main
Changing that to deb-src icinga-focal main…

Installer runs now, I think I can continue … thanks!


Sometimes it’s that simple!
Congrats that you found the culprit.

All the best
