Error: repository is no longer signed

I’m running a node built on the AllStarLink ASL 2.0.0-beta image which I keep up to date approximately weekly. Today, I went to update it with sudo apt update and received this message in the output:

E: The repository ‘http://apt.allstarlink.org/repos/asl_builds buster InRelease’ is no longer signed.

I did find the curl statement to use to update the key at Public Key not available? - #4 by Bob_Pyke but when I pasted that command string into PuTTY, I got this:

gpg: no valid OpenPGP data found.

Any other hints on how to update the repository signing key on my node so that I can run an update?

Thanks,

Does this work for you?

apt update
apt install curl gpg
cd /tmp
wget http://apt.allstarlink.org/repos/asl_builds/install-allstarlink-repository
chmod +x install-allstarlink-repository
./install-allstarlink-repository

The usual sudo apt update worked today. I wonder if this was just a connectivity issue that has since been resolved.
