#1199 Change base image to use focal instead of jammy

[jheinitz]

hello,

I have changed the base image to use the focal instead of jammy. This fixes issue #1199

Would be great if you could also perform some tests and merge this PR into your repo.

Thanks and kind regards

Jens

Not really sure downgrading will be a final solution (just a temporary patch that will failed in long term when we will have to upgrade).

Can you simply start docker run -it eclipse-temurin:11-jre bash and try java -version, if it's not work, the issues is on downstream and you can report the issue here?

This is what I get:

Hi,

it seems to be a problem with the docker version. I can confirm for RedHat that it works on RedHat 8.6 with a newer docker version than on RedHat 8.5. Please see this comment for details.

Cheers

Jens
