Hi,
Not sure if this is really a Docker question, or Ubuntu or perhaps Vagrant.
When a script inside a docker image that I’ve acquired starts up I get the following error message during apt-get update.
W: GPG error: http://archive.ubuntu.com/ubuntu xenial InRelease: Could not execute ‘apt-key’ to verify signature (is gnupg installed?)
W: The repository ‘http://archive.ubuntu.com/ubuntu xenial InRelease’ is not signed.
(repeated a couple more times, with very similar output)
Has anyone else come across this before? After this step, all the apt-get install steps fail because they don’t have the correct key, unless you specify --allow-unauthenticated.
Many thanks,
