This GitHub issue claims you just need to install the rpm, enable the service and reboot, has anything changed in the meantime?
In my limited experience with Tailscale, it was about that simple back then, at least.
Trying to install the rpm manually by layering it just errors out for me. Someone else on here said that for him it bricked his entire system, so I’m not exactly fond of attempting to brute force it - especially with 4 year old instructions for another distro.
You’re literally replying to my comment stating how I tried that and how it bricked someone’s system.
