Is Oracle Linux install supported?

Hi, I am trying to install on Oracle Linux 8 [Download · Tailscale], both on x86 and Arm, both tries with “one command” and by “adding repo”. No matter what I try, I am facing problems, i.e.:

Authorization failed.
    Make sure polkit agent is running or run the application as superuser.

Error: Failed to download metadata for repo 'pkgs.tailscale.com_stable_oracle_8_tailscale.reposudo': Cannot download repomd.xml: Cannot download repodata/repomd.xml: All mirrors were tried

Could you pls confirm that the install is working correctly?

Did additional tests on clean VMs. All seems to be working fine. Thanks.
