GPG Download instructions are not working

[mrexodia]

In the documentation at https://www.zerotier.com/download/ there is a section about import GPG keys for Debian. It looks like the branch got renamed from master to main, so these instructions do not work.

Had the same issue just now
Tested in fresh install of Proxmox 8.1 / Debian 12, see part of the error below

Hello - I noticed this issue as well @mrexodia and @monnoval - GitHub will actually redirect the links properly (see for example the https://github.com/zerotier/docs repo, it has references to master branch all over) :)

Not sure where Zerotier maintains their website, is that open source? Happy to make a PR with the fix, if so.

Otherwise, here is the solution - the issue was that the GPG key name was renamed from contact@www.zerotier.com.gpg to contact@zerotier.com.gpg:

curl -s 'https://raw.githubusercontent.com/zerotier/ZeroTierOne/main/doc/contact%40zerotier.com.gpg' | gpg --import && \  
if z=$(curl -s 'https://install.zerotier.com/' | gpg); then echo "$z" | sudo bash; fi

In the meantime until the docs are updated, this should be an acceptable workaround. The branch naming change is optional ofc, but I personally don't like relying on a redirect from GitHub.
