Am I missing something, or will ZeroTier not be supported for use on KDE Neon?
The snap packages are dated 2022 and the Zerotier installer bombs out with
“Unknown or unsupported distribution! Aborting.”
You could be missing something provided by the ubuntu-minimal
or ubuntu-standard
metapackages, so do this:
apt install ubuntu-standard
And report this:
lsb_release -a
uname -a
And report the whole installation transcript for the upstream package.
The official ZeroTier package is better because the Ubuntu snap package is unmaintained.
