Repository is not signed #2
Description
Hey there. Appreciate this is an old repo, but wondered if you'd be interested in fixing this. I am using this image via docker-xpra-html5-minimal. When I first run apt-get update I get the error
8.960 W: GPG error: http://xpra.org focal InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 73254CAD17978FAF
8.960 E: The repository 'http://xpra.org focal InRelease' is not signed.
It looks like their is a new method of adding the repo potentially https://github.com/Xpra-org/xpra/wiki/Download#-for-debian-based-distributions
