gpg: refreshing 9 keys from hkp://keyserver.ubuntu.com gpg: keyserver refresh failed: Connection timed out -- due to an Ubuntu outage

[jsoref]

Describe the bug

GitHub runners are having trouble talking to the ubuntu keyserver, this is due to an Ubuntu outage.

If this is going to be a long term problem, and this were my action, I'd probably add code to detect the server being broken and provide a message, or consider not relying on it or something. At the very least, I'd open a ticket so people could see that it's a known issue.

I'm not sure that there's anything that setup-swift can do about this, but i'm not sure that there isn't, and the action says to report it:

Export file baseline information (ubuntu-latest, nightly-latest)

Unexpected error, unable to continue.
