@cmcgee1024 This is the same error I received.
I got around this by running the install script again

[cmcgee1024]

@Nobody1707 and @wangzhizhou, does manually adding the swift.org keys help to work around the problem?

curl --silent --retry 3 --location --fail https://swift.org/keys/all-keys.asc | gpg --import -

This is what the swiftly install script does to import the swift.org keys. It's just that there are new keys for the 6.x toolchains.

[Nobody1707]

Yes, it updated successfully after manually adding the keys.

Should I be worried about the warning?

Thanks @Nobody1707 for confirming that the workaround is working.

In terms of the warning, this is expected. You can see a note about it in the Linux toolchain download instructions here on the swift website: https://www.swift.org/install/linux/tarball/
