This bug is not reproduced on Windows.

We recommend installing workload sets that match the band you're in. Is there a reason you can't install 9.0.200 workload set?

[YingyingYuan9]

the scenario supports updating to a workload sets from a different band. so we tried to Dotnet workload update --version 9.0.101, it failed.
if we run Dotnet workload update --version 9.0.200, it can succeed

I spent entirely too much time working on this before realizing that I'd already fixed this in 9.0.3xx:
#46351

I confirmed that that fix works.

@baronfel, do you think this is worth backporting? I'm slightly leaning towards 'no' but would be happy to backport it if you think it's worth it.

@YingyingYuan9,

Thanks for bringing this up! We decided we're not going to take this for 9.0.2xx, so I'm closing this as won't-fix. Going forward, you can skip this test for 9.0.2xx and just run it for 9.0.3xx and later versions.
