Cannot update LEMP-STACK

1. Created new antlet with lemp-stack template.
2. SSH to 10.1.1.xx & login
3. apt update

Expecting no errors.

Ultimately I am wanting to install JAVA but encountered errors on the first step towards the objective.

Any suggestions as to what needs to be done before the template itself is updated?
