@aik-jahoda did you run a manual runtime build from your branch? It seems like opensuse is missing fonts and the System.Drawing.Tests are failing because of that.

[aik-jahoda]

@safern All test are passed and we can merge it. Can you please review?

@safern @ericstj can you please review the PR? Then we can merge (and backport to .NET 6.0). Thanks!

From previous review:

did you run a manual runtime build from your branch?

I looked through the logs from this PR to find where this is running on the queue you added and can't find it:
https://dev.azure.com/dnceng/public/_build/results?buildId=1484879&view=logs&j=71afe768-e493-597c-228c-037834193aeb&t=fe87d331-02fa-5ca6-e382-69b0a11bb0f6

Perhaps you can share the link to the build which tested your changes?

[aik-jahoda]

@krwq I'm little bit lost with build, I have followed your suggestion from #60054 (comment) however I can't see any openSUSE tests:
https://dev.azure.com/dnceng/public/_build/results?buildId=1490317&view=results

Could it be caused by ne(parameters.jobParameters.isSingleFile, true) when this branch contains change only on one file?

[safern]

I don't think we need to touch another file. Where did you see that condition?

The change looks good, I just triggered another pipeline and when done I can help you getting the open suse test results:
https://dnceng.visualstudio.com/public/_build/results?buildId=1494706&view=results

[aik-jahoda]

Test results: https://dnceng.visualstudio.com/public/_build/results?buildId=1494706&view=logs&j=b9b7de4d-2126-5581-6453-1576f9aaac5f&t=db048d48-40e8-5399-9b14-d587763f33ff&l=49

There is failing ubuntu arm, however it is unrelated: #60825

[safern]

Mono runtime tests are also unrelated.
