Can't install on RHEL 8: bad GPG signature

Stock RHEL 8, up-to-date, but there’s a bad signature on ‘tailscale-stable’. Any ideas? Thanks.

I ran in to the same problem. I filed a bug report, it will be updated here:

In the meantime, if you have already run the install.sh script, and it has failed. You can manually run:

sudo yum install tailscale

It will prompt you to accept the repository key, then install it.

You will then have to start with:
sudo systemctl start tailscaled
tailscale up

And proceed as normal.
