Bug report summary

Hello! While reinstalling Netdata on two Ubuntu systems with the Kickstart script, I noticed that in some parts, the script fails to display a line break properly, instead showing a literal \n:

OS / Environment

Netdata version

Component Name

Steps To Reproduce

1. Execute the kickstart.sh file as instructed here (in my case I supplied --stable-channel --disable-telemetry as arguments)
2. Follow the installation instructions and watch.

Expected behavior

You should see the line breaks working correctly.

Hi @NinoM4ster this was already fixed by was already fixed by #8326 #8325 and #8324 So if you remove the --stable-channel option you won't see this. That being said I've put up #8447 to improve this a bit more as well as #8446 that applies similar fixes for the uninstaller.

Thanks for reporting!
