can you help me please

There is no checkmk package available for Ubuntu 21.10 (yet).

Aww Crud.

I just got finished setting up an ubuntu 21.10 vm to run Checkmk and had the same problem.

Did you find a way to get it going or do I have to start over? :frowning:

You have to start with other distribution version.
What i cannot understand is, why does someone install a server software that runs longer than some months on a operating system that only gets support for 9 months?


It’s just habit to grab the newest release of a software when starting a new project for most people. For some of us, diving into a project and dealing with issues as they come up is our way of learning, knowing that we should have researched it beforehand. ¯_(ツ)_/¯.

Before going the “try and fail” route I read the requirements of a software. And obviously each checkmk package is for a specific distribution version. If there is none available for the intended target distribution I cannot install the software.
