Update debpkg container image to ubuntu 18

[am11]

Ubuntu 14 is out of support. Update to latest available debpkg container.

[dotnet-issue-labeler]

I couldn't figure out the best area label to add to this PR. If you have write-permissions please help me learn by adding exactly one area label.

Why not even further like 20 or even 22?

[am11]

We currently do not have images higher than Ubuntu 18, with debpkg prereqs installed. I have just updated to the latest available image in order to abandon Ubuntu 14.

Good point tough. We can send a PR to build one with 22.04 (similar to https://github.com/dotnet/dotnet-buildtools-prereqs-docker/blob/66216d372d2f80144b6a53535a46f2c7ced0d17e/src/ubuntu/18.04/debpkg/Dockerfile), that will buy us couple of more years.

It looks good to me, but I don't have time to pull down packages to verify. @NikolaMilosavljevic can you take a closer look?

[NikolaMilosavljevic]

@am11 have you verified that packages are being produced? When I attempted similar change last year, installer build succeeded but did not produce any DEB packages. Perhaps this is a newer docker image and works well.

[am11]

@NikolaMilosavljevic, from the CI logs, we see:

  dotnet-runtime-deps-debian -> /root/runtime/artifacts/packages/Release/Shipping/dotnet-runtime-deps-7.0.0-ci-x64.deb

Build succeeded.
    0 Warning(s)
    0 Error(s)

in both main and PR legs. Do you have any specific validation method in mind? I can build them locally and compare file sizes in the tree, for example.

That's great. The only validation I would suggest, would be to download produced DEBs (or build them locally) and try to install on a repro machine/container.

Packages (.deb) are produced but they are not uploaded to build artifacts (only log files are uploaded). This is the case with both:

• main branch with Ubuntu 14.04: https://dev.azure.com/dnceng/public/_build/results?buildId=1730882&view=logs&j=7f5ce049-9fcc-50f8-e470-d8e52687d56a&t=d71fcd51-a472-5d5e-3f5a-e482fbd6ea4b

• and this PR with Ubuntu 18.04: https://dev.azure.com/dnceng/public/_build/results?buildId=1731561&view=logs&j=7f5ce049-9fcc-50f8-e470-d8e52687d56a&t=d71fcd51-a472-5d5e-3f5a-e482fbd6ea4b

[am11]

@ViktorHofer, @hoyosjs, do you know if we can get pipeline to upload artifacts (one off), so we can verify the produced package dotnet-runtime-deps-7.0.0-ci-x64.deb from Package Runtime Deps, Runtime, Framework Packs installers - deb step is valid?

(ideally we should have a build step to install the produced deb and rpm in clean containers to automate this verification process..)

[ViktorHofer]

Probably by removing this if:

runtime/eng/pipelines/installer/jobs/steps/upload-job-artifacts.yml

Line 10 in e386044

- ${{ if eq(parameters.isOfficialBuild, true) }}:

[am11]

Thank you. I have inverted the condition temporarily so we can test the *.deb artifacts.

[am11]

@NikolaMilosavljevic, the intermediate artifacts archive that has deb file was uploaded by the last run here: https://dev.azure.com/dnceng/9ee6d478-d288-47f7-aacc-f6e6d082ae6d/_apis/build/builds/1756291/artifacts?artifactName=IntermediateArtifacts&api-version=7.0&%24format=zip (size: 7.2 GB)

I have successfully installed the .deb file on Ubuntu 22.04, 20.04 and 18.04 and executed a few commands, it works.
e.g. on 20.04:

$ cd extract_dir_of_selected_files_from_screenshot
$ docker run -v$(pwd):/assets1 -it ubuntu:20.04

# inside the container
$ apt update && apt install -y libicu-dev libkrb5-dev
$ cd /assets1
$ dpkg -i *.deb

@hoyosjs I see that you have already updated it to Ubuntu 18 in 6bc1c94. I have bumped to the latest prerequisite ref.
