GPG key seems to be the wrong one

[rrthomas]

Describe the bug
Having downloaded the PGP key block xpra.asc file as instructed for Debian-based distros (Ubuntu 22.04 in my case), I get:

W: An error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: https://xpra.org jammy InRelease: The following signatures were invalid: EXPKEYSIG 18ADB31CF18AD6BB Antoine Martin <[email protected]>
W: Failed to fetch https://xpra.org/dists/jammy/InRelease  The following signatures were invalid: EXPKEYSIG 18ADB31CF18AD6BB Antoine Martin <[email protected]>

Additional context
What is odd is that when I had this problem some weeks ago on another machine, I downloaded the file again and got a newer one (datestamp March 24th 2022). This appears to be the right one, as it contains the key referred to, whereas the file currently available does not.

@totaam: thanks, the key seems to have been updated once more; did you do something? What I was trying to explain above is that when I downloaded the key about two weeks ago, I got the same key as now. But when I downloaded it two days ago, I got an older key.

@rrthomas perhaps this answers your question?

Ah yes, thanks! So that means that the key has been updated, and this issue can be closed?

Different distribution releases require different keys.. so I have tried not to update existing files and change URLs to new ones instead, in the (perhaps foolish) hope that this would not break existing workflows.
