LsAgent is not picked up on Ubuntu server

[FrederickCoene]

I seem to experience the same issue as on:
https://www.lansweeper.com/forum/yaf_postst17502_LsAgent-on-Ubuntu-18-04---Not-getting-updated-in-the-console.aspx#post58716

I installed the LsAgent on an ubuntu node, but it isn't picked up by Lansweeper.
I can't find the node in "Scanning"/"LsAgent Scanning" section.

How can this issue be solved?
I don't have any specific exclusion reasons set on lansweeper.
