I modified the /etc/apt/sources.list.d/sonatype-community.list file and changed first line to include [arch=all trusted=yes].
Then apt update worked albeit with a warning.

Worth noting when upgrading that 3.70.X is not provided in the repo and will attempt to update from 3.69.X direct to 3.71.X which will not work.

Issue still present to me, any news on this?
