Apt-get install monitoring-plugins -> package cannot be found (Ubuntu 18.04 live-server)

Hi and happy new year to all!

“apt-get install monitoring-plugins” works perfectly in Ubuntu 19.04 live server Now I wanted to use the same in 18.04.1 Live-Server. But the following error message appears: “Package monitoring plugins cannot be found.” (Paket monitoring-plugins kann nicht gefunden werden).

Under /etc/apt/sources.list.d is “bionic-icinga.list bionic-icinga-snapshots.list” located.


deb http://packages.icinga.com/ubuntu icinga-bionic main
deb-src http://packages.icinga.com/ubuntu icinga-bionic main


deb http://packages.icinga.com/ubuntu icinga-bionic-snapshots main
deb-src http://packages.icinga.com/ubuntu icinga-bionic-snapshots main

Can someone help me out?

Hmm, I have made an “icinga2.list” folder and put the bionics in there.

echo “deb http://packages.icinga.com/ubuntu icinga-bionic main” > /etc/apt/sources.list.d/icinga2.list
echo “deb-src http://packages.icinga.com/ubuntu icinga-bionic main” >> /etc/apt/sources.list.d/icinga2.list

same problem.


monitoring-plugins are not coming from packages.icinga.com, but from official ubuntu repository.

Ok and what is the solution? In the docs is only “apt-get install monitoring-plugins” written.

I would say, that there is something wrong with your default repository configuration. Maybe some repositories are missing or you have a syntax error in one of your files.

I’ve checked it serveral times. I will just install everything again in a new VM.


There it is. so it should work. If you copy&pasted it from the doku, try typing it by hand.

IIRC universe is sometimes not enabled in the Ubuntu package list sources in /etc/apt/sources.list*.


allready did that, same problem. I think that something basically went wrong with the installation.

I will check it. Thanks!

With the information provided above, you can look into the path and search for universe as repository. My guess is that it is not enabled.
