Dedicated Server support for Linux is not installed after updating from 2022.3.16f1 to 6000.0.0f1

Bug description

Linux server build fails in GitHub Actions after update of Unity Editor version from
unityci/editor:ubuntu-2022.3.16f1-linux-il2cpp-3.0.1
to
unityci/editor:ubuntu-6000.0.0f1-linux-il2cpp-3.0.1

Error:

#152 142.8 Error building Player: Dedicated Server support for Linux is not installed.

How to reproduce

Run build of Unity project in container.

# linux-specific Unity build
FROM --platform=$BUILDPLATFORM unityci/editor:ubuntu-6000.0.0f1-linux-il2cpp-3.0.1 AS build-unity-linux
WORKDIR "/src"
COPY --from=build-dependencies /src/src/SomeProject/ .
RUN --mount=type=secret,id=UNITY_USERNAME \
    --mount=type=secret,id=UNITY_PASSWORD \
    --mount=type=secret,id=UNITY_LICENSE \
    unity-editor -quit -batchmode -serial $(cat /run/secrets/UNITY_LICENSE) -username $(cat /run/secrets/UNITY_USERNAME) -password $(cat /run/secrets/UNITY_PASSWORD) && \
    unity-editor -quit -batchmode -nographics -buildTarget Linux64 -standaloneBuildSubtarget Server -executeMethod Builder.Build -projectPath . && \
    unity-editor -quit -batchmode -returnlicense -username $(cat /run/secrets/UNITY_USERNAME) -password $(cat /run/secrets/UNITY_PASSWORD)

Expected behavior

Build should succeed.

Previously used

FROM --platform=$BUILDPLATFORM unityci/editor:ubuntu-2022.3.16f1-linux-il2cpp-3.0.1 AS build-unity-linux

Additional details

I'm on MacOS so grabbing a Windows Machine to try to repro locally for more details. Currently running in GH Actions, where build had been working until version change.

Perhaps tied to regex check for version before installing server modules:

RUN echo "$version-$module" | grep -q -vP '^(2021.2.(?![0-4](?![0-9]))|2021.[3-9]|202[2-9]|20[3-9]).*linux' \
  && exit 0 \
  || unity-hub install-modules --version "$version" --module "linux-server" --childModules | tee /var/log/install-module-linux-server.log && grep 'Missing module' /var/log/install-module-linux-server.log | exit $(wc -l);

RUN echo "$version-$module" | grep -q -vP '^(2021.2.(?![0-4](?![0-9]))|2021.[3-9]|202[2-9]|20[3-9]).*windows' \
  && exit 0 \
  || unity-hub install-modules --version "$version" --module "windows-server" --childModules | tee /var/log/install-module-windows-server.log && grep 'Missing module' /var/log/install-module-windows-server.log | exit $(wc -l);

https://github.com/game-ci/docker/blob/main/images/ubuntu/editor/Dockerfile

Something like this would work to cover version 6+ and 10+ assuming this version style is maintained.

Regex addition:

^([6-9][0-9]{3}|[1-9][0-9]{4,}).*

• Any 4-digit version starting from 6000 up to 9999.
• Any 5-digit or larger version number starting from 10000 and upwards

Makes the final pattern a bit gross but likely works, haven't tested yet.

POTENTIAL SOLUTION:

RUN echo "$version-$module" | grep -q -vP '^(2021.2.(?![0-4](?![0-9]))|2021.[3-9]|202[2-9]|20[3-9]|[6-9][0-9]{3}|[1-9][0-9]{4,}).*linux' \
  && exit 0 \
  || unity-hub install-modules --version "$version" --module "linux-server" --childModules | tee /var/log/install-module-linux-server.log && grep 'Missing module' /var/log/install-module-linux-server.log | exit $(wc -l);

RUN echo "$version-$module" | grep -q -vP '^(2021.2.(?![0-4](?![0-9]))|2021.[3-9]|202[2-9]|20[3-9]|[6-9][0-9]{3}|[1-9][0-9]{4,}).*windows' \
  && exit 0 \
  || unity-hub install-modules --version "$version" --module "windows-server" --childModules | tee /var/log/install-module-windows-server.log && grep 'Missing module' /var/log/install-module-windows-server.log | exit $(wc -l);

I actually discovered this a few hours ago while trying to fix the android modules. Your regex is much better than what I had though so I went ahead and incorporated it into my branch. Will try to fast track this to a release. Thanks for chasing this down!

[AndrewKahr]

The fix is live for Unity 6 images. Check to see if dedicated server is working for you now and if it is we can close this issue

#146 144.2 Asset Pipeline Refresh (id=905952f5a7a50c95394e27c5dcd177f1): Total: 0.022 seconds - Initiated by StopAssetImportingV2(NoUpdateAssetOptions)
#146 144.2 Error building Player: Dedicated Server support for Linux is not installed.

Maybe the image isn't built out yet?

[AndrewKahr]

That's odd I see this in the build log: [Linux Dedicated Server Build Support] installed successfully.
Maybe pull the image locally and manually check the expected files exist for it?

[AndrewKahr]

Also make sure you're using the updated image version. Not sure if you've pinned it to 3.0.1 or if that's just what was latest when you ran it. It should be 3.1.0 now

[paulbreuler]

That's probably it!

[paulbreuler]

That did the trick. I didn't see docs on pinning versions. I just noticed in unityci/editor each image has the version in the name.

Is there a string I should use to just pull the latest?

Updated to -3.1.0

If you use just 3 as the version it will be the latest version with a major version of 3
