Dependencies broken in latest ubuntu (22.04) #57

Open clagms opened 1 year ago

clagms commented 1 year ago

It seems that if Rabbitmq is loaded in a dockerfile like the following, it will fail due to missing dependency:

FROM ubuntu:latest

RUN apt-get update && apt-get install -y openjdk-11-jdk wget tzdata

RUN DEBIAN_FRONTEND=noninteractive && apt-get install -y tzdata

CMD tail -F anything

As of today, the latest ubuntu is 22.04

It will give the following error:

@gitting-around is there any way to fix these dependency issues once and for all? It's a nuissance that whenever a new ubuntu version comes about, we risk breaking rabbitmqfmu loading behavior.

Can we at least set up integration tests that will catch these problems? They are fairly easy to reproduce: just get a docker with latest ubuntu, and run a cosim with rabbitmq and some script generating messages.

The workaround to this issue is to change the dockerfile above with the following:

FROM ubuntu:22.04

RUN DEBIAN_FRONTEND=noninteractive

RUN apt-get update && apt-get install -y openjdk-11-jdk 

# Fixes https://github.com/INTO-CPS-Association/fmu-rabbitmq/issues/57
RUN echo "deb http://security.ubuntu.com/ubuntu focal-security main" | tee --append /etc/apt/sources.list

RUN apt-get update && apt-get install -y libicu66 libssl1.1 

CMD tail -F anything

Maybe RabbitmqFMU needs to be updated to use the most recent openssl? It seems the intention is to move away from openssl1

I just noticed that this seems to be a duplicate of https://github.com/INTO-CPS-Association/fmu-rabbitmq/issues/56 and https://github.com/INTO-CPS-Association/fmu-rabbitmq/issues/54.

I hope we can find another solution to prevent this from reocurring whenever ubuntu changes.
