[Andreas Ufert (andreas.ufert)]

The patch attached by brunoqc solves the problem for me.

[DipSwitch (nick-ds)]

I use the following patch. This also works.

[Matija Nalis (mnalis)]

brunoqc diff also works for me. Seems easy fix, why not apply it?

[Matija Nalis (mnalis)]

this patch is improved version of brunoqc patch, allowing also for version names containing "~", like:

Linux version 4.2.0-42-generic (buildd@lgw01-55) (gcc version 4.8.4 (Ubuntu 4.8.4-2ubuntu1~14.04.3) ) #49~14.04.1-Ubuntu SMP Wed Jun 29 20:22:11 UTC 2016 (Ubuntu 4.2.0-42.49~14.04.1-generic 4.2.8-ckt12)]

[Jan Wagner (waja)]

Is this still an issue on recent distributions?

[Bruno Bigras (brunoqc)]

No idea. I don't use this software anymore.

Just checked it out and it still happens on 20.04:

[Jan Wagner (waja)]

With recent, I was not talking about 20.04, which is NOT recent. See https://launchpad.net/ubuntu/+source/nagios-plugins-contrib for newer releases.

(speaking with my debian maintainers hat on, I'm not feeling responsible for fixing bugs in ubuntu)

[Jan Wagner (waja)]

FYI: I added the patch from mnalis about the additional tilde in the version string to the debian package
