dotnet workload install wasm-tools does not install on Linux

[Aculeo]

I run sudo dotnet workload install wasm-tools, it says that installation was successful.
When I then run dotnet workload list it shows no workloads.

Output of installation:

$ sudo dotnet workload install wasm-tools

Aha, found a resolution: I decided to ditch the SDK bundled with Ubuntu, and installed it through the MS package feed. And now it correctly installs. I would suggest documenting this somewhere perhaps? I think the issue can be closed though.

For anyone wanting to switch to Microsoft feed as well:

1. Follow instructions here: https://learn.microsoft.com/en-us/dotnet/core/install/linux-ubuntu#register-the-microsoft-package-repository
2. Ensure the new package repo is pinned, or you'll get some funny errors: https://stackoverflow.com/questions/73753672/a-fatal-error-occurred-the-folder-usr-share-dotnet-host-fxr-does-not-exist

[tmds]

Installing a workload with the a bundled SDK should work by leaving out sudo:

dotnet workload install wasm-tools

MS builds require sudo to be able to add files to locations which are only meant for package installs.

[Aculeo]

I tried it without sudo as well, didn't work either

This is what I get when using the distro packages on Fedora:

Can you share the output of:

find $(dirname $(readlink $(command -v dotnet))) -name userlocal

This should find a file at <DOTNET_ROOT>/metadata/workloads/6.0.100/userlocal.

[Aculeo]

Hi, as I've already switched to the MS package feed I can't test this, but perhaps I can try this on another device

Good. This makes install work without sudo.

I imagine this happens because you ran the command with sudo previously.

Try this:

Thanks, it worked! And now it lists the installed workloads:

Great!

For some extra context: when the installable workload feature got added to the sdk, we wanted to avoid the sudo install in source-built .NET because it adds files to the system dotnet location.

A source-build sdk includes a userlocal file which causes the workload to be installed in a user folder instead.

See #18104 and #18823.

[mirespace]

Hi @tmds,

I was checking different installations to see if this is something we must consider from the debian packaging/installation point of view, and I reproduced the issue in a LXC container (Ubuntu Jammy) with our lastest ubuntu debs from ubuntu.archive : installed successfully, but the listing doesn't.

and a file for wasm-tools as a installed workload can be found at:
