" To see the full list of approved methods for each operating system/version we support, see our distribution matrix."
If this is not supported, why is your team putting effort into creating these repositories and then documenting how to install Netdata with it? I understand that documentation isn’t always up to date and correct, but it very strongly implies that there is no real downside to using .deb other than you cannot use Xenstats & AWS Kinesis as indicated on the distro matrix page I linked.
If I MUST use kickstart.sh to get any sort of support, I can accept that this one node just will never work. Sorry to waste your time but I’m not interested in installing software outside of my package manager as a general rule. I would lightly suggest putting warnings on the pages I linked that despite it being in your documentation, that it is not recommended and that no support is available if you follow those instructions to install netdata. Even just yellow “Yield” icons or something to scare people away from using them would seem appropriate and probably lead to less of your users installing Netdata in ways you actually don’t want us doing.
You can probably also delete my other support thread as that server also was installed via APT using your packagecloud repo and so it’s probably useless to you:
