Maybe I'm looking at the wrong problem, but it seems like maybe tailscale changed how the serve command works and what flags it supports? I have a fedora server 43 box running tailscale installed with dnf install tailscale, and it's version 1.84.1, and it seems to not support the --service flag, so when I run sudo tailscale serve --service=svc:music --https=443 127.0.0.1:4533 - I just get the help output because it's an invalid flag.
No worries, I'll just update the version of tailscale... except I guess maybe I won't, because fedora says I'm already at the most recent version. I looked into a tailscale yum repo and found one, but it only has fedora versions up to 39. I don't honestly know tailscale well enough to know if it would be problematic to try updating 43 from a 39 repo, but I assume the different fedora versioned repos exist for a reason 🙂
So what's the recommended approach here?
