[BUG] 'To build this project, the following workloads must be installed: maui-android', but the workload is already installed

[anpin]

Describe the bug

I'm not able to restore/ build MAUI project targeting net8.0-android on linux. The message says I need to install net8.0-android even though it is already installed.

To Reproduce

The repro is located here and it is using the nix package manager to setup developer environment with dotnet and userlocal files as per #18823.

git clone https://github.com/anpin/maui-on-nix
cd maui-on-nix
nix develop 
dotnet workload restore 
dotnet restore

Exceptions (if any)

not able to reproduce it in docker with ubuntu (the reproduction repo was updated with dockerfile), so it must be nixos specific

[anpin]

@baronfel can you give any advise on how to investigate it further please?

[SylvainGantois]

Same problem on Ubuntu

Same problem on Ubuntu

Interesting. Would you mind sharing how your environment is setup and if it is anywhere close to the docker file in my reproduction repo?

[SylvainGantois]

ok, my bad, it actually worked but I had to:

• follow the instructions here: Workload ID maui-android is not recognized #38171 (install via script and copy the sdk-manifests folder) files
• remove net8.0-ios and net8.0-maccatalyst from the targets of the project
• build using dotnet build, by using Rider I get the following:
  1>Microsoft.NET.Sdk.ImportWorkloads.targets(38,5): Error NETSDK1147 : To build this project, the following workloads must be installed: maui-android To install these workloads, run the following command: dotnet workload restore 1>Microsoft.NET.Sdk.ImportWorkloads.targets(38,5): Error NETSDK1147 : To build this project, the following workloads must be installed: maui-tizen To install these workloads, run the following command: dotnet workload restore

@GaijinFizz thanks for linking the issue, I was not aware of it. Looks to me like the the sdk ignores $DOTNET_ROOT/metadata/workloads/8.0.100/userlocal at some stage and instead of looking for installed workloads in $HOME/.dotnet looks at /usr/[lib|share]/dotnet which is not present on nixos. However, some users are reporting that the workaround used in the reproduction repo works for them, please see this thread

[anpin]

Actually I'm wrong, by quickly searching for /usr/lib I have found that it comes from the $DOTNET_ROOT environment varaible

I had to create /usr/share/dotnet before copying sdk-manifests, it's worth a try :)

[Mr-MooMoo]

I think i face the same problem.

'dotnet workload install aspire" (or any other dotnet workload install or update command) results in:
Workload installation failed: Read-only file system : '/nix/store/g2mws5h1b3n08mfcxplfa98mf0rgr68p-dotnet-core-combined/metadata/workloads/8.0.300/InstallState',

although I have a file 'userlocal' present @ '/nix/store/g2mws5h1b3n08mfcxplfa98mf0rgr68p-dotnet-core-combined/metadata/workloads/8.0.300/userlocal' , which (as far as i understood) should force sdk to install workloads in my $HOME/.dotnet folder..?

[baronfel]

@Mr-MooMoo this is a side effect of the workloads sets feature we're working on I believe. @dsplaisted / @Forgind do we check where the install state should be written to for the user local workload scenario? If not I think we should.

[anpin]

@Mr-MooMoo do you have $DOTNET_ROOT env variable set?

In my case installation completes successfully and files are present in ~/.dotnet, but sdk fails to run restore/build/etc
