PX2 after flashing 5.0.10.3, can not install openjdk8 JRE

Hi,
after flashing to Drive OS 5.0.10.3 with with SDK Manager,
I need to install OpenJDK 8 JRE,
but this fails with
sudo apt-get install openjdk-8-jre

The following packages have unmet dependencies:
 openjdk-8-jre : Depends: openjdk-8-jre-headless (= 8u282-b08-0ubuntu1~16.04) but it is not going to be installed
                 Recommends: fonts-dejavu-extra but it is not installable
E: Unable to correct problems, you have held broken packages.

sudo apt-get install openjdk-8-jre-headless

The following packages have unmet dependencies:
openjdk-8-jre-headless : Depends: java-common (>= 0.28) but it is not installable
E: Unable to correct problems, you have held broken packages.

sudo apt-get install java-common

E: Package 'java-common' has no installation candidate

Searching the internet does not reveal a straight-forward solution, so,
if someone has found a way to properly install the JRE, its solution would be appreciated.

Dear @hermann.f,
Firtstly, Do you see any issues with sudo apt-get update? May I know why you are trying to install openjdk?

Dear @SivaRamaKrishnaNV,
I already have done an apt-get update before trying to install it.

The reason why I want to install a JAVA runtime is, that before flashing the PX2 to Drive OS 5.0.10.3, I have had a running JAVA app, that triggered the recorder for 8 cams plus GNSS recording plus NTP setup in the field and worked quite well.

After flashing, I wanted to unify all these things into a single C++ app - based on the up-to-date sample codebase, but failed epically. Since I cannot afford to spend more time on this, I want to restore the previous workflow.

Dear @hermann.f ,
Currently, I could not test on DPX2. But could you check aarch64-port/jdk8: 9a781f9c1338 / if it helps?
