UnauthorizedAccessException during compilation with 2021.2.0

[KuraiAndras]

Bug description

I upgraded one of my projects to 2021.2.0. Everything works in the editor, but the CI build fails

How to reproduce

• Create a unity build with 2021.2.0

Expected behavior

Project builds without error

Additional details

I'm using the image: unityci/editor:2021.2.0f1-windows-mono-0.15.0

When running the build on Windows and installing Unity via chocolatey, everything works as expected

[davidmfinol]

@KuraiAndras Are you still facing this issue? If you are, I'd recommend trying to build on a Linux PC or VM to see if that works.

[KuraiAndras]

I think it was present until 2021.2.2, but I am not sure. I switched to building on windows, and installing unity using chocolatey. I will try it again soon.

[KuraiAndras]

Yup, I just tried it with 2021.2.4

@KuraiAndras I have seen other users able to build with 2021.2 now, so I'm wondering again if this is still an issue for you?
If so, can you share more details about your project (preferably a minimum, complete, verifiable example) to see if we can identity what is wrong?

[davidmfinol]

Closing due to lack of steps to reproduce; please re-open if MCVE is provided.

This is reproducible if you run a docker image on Linux GHA as a non-root user. E.g. here: https://github.com/getsentry/sentry-unity/actions/runs/3283416099/jobs/5408100927

docker run -td --name unity --user $(id -u):$(id -g) .... unityci/editor:ubuntu-2021.3.11f1-base-1.0.1
docker exec unity dotnet msbuild /t:UnityConfigureSentryOptions /p:Configuration=Release /p:OutDir=other src/Sentry.Unity

Adding docker exec --user root unity chmod -R 755 /opt/unity/Editor/Data/UnityReferenceAssemblies/ works around the issue - I guess it could be added to the docker build itself?

This applies to Unity 2021(.3.11) & 2022(.1.20)
