The Package name seems to be wrong:
openjdk-11-jre-headless_11.0.9.1+1-0ubuntu1~20.04_arm64.deb
Name in http://ports.ubuntu.com/ubuntu-ports/pool/main/o/openjdk-lts:
openjdk-11-jre-headless_11.0.9+10-0ubuntu1_arm64.deb
Problem solved:
Booting the Ubuntu system the timedate service didn't work (bug?). The date was one year behind. Therefore some certificates failed and thus some connections to repositories.
I changed timedate to ntp and all works fine!
$ sudo timedatectl set-ntp no
$ sudo apt install ntp
$ ntpq -p
$ date
