Hey

I'm getting a very similar issue.

Trying to upgrade from preview 6 and have already installed maui-check 7.3.0.

I've already updated to VS 2022 Preview 3 and running maui-check results in it trying to repair the workload installation for maui.

My error is very similar to @davidbuckleyni's:

Workload repair failed: The JSON value could not be converted to Microsoft.NET.Sdk.WorkloadManifestReader.WorkloadPackId. Path: $.Id | LineNumber: 0 | BytePositionInLine: 40.

Installation continues but results in the following:

Fix failed - Workload Update failed: `dotnet workload update --sdk-version 6.0.100-preview.7.21379.14 --no-cache --disable-parallel --from-rollback-file
"C:\Users\Paul\AppData\Local\Temp\maui-check-dotnet-work-dir\workload.json" --source "https://api.nuget.org/v3/index.json" --source
"https://pkgs.dev.azure.com/dnceng/public/_packaging/6.0.100-preview.7.21379.14-shipping-1/nuget/v3/index.json"`

This attempt was using the --force-dotnet switch. I had a previous failure where the configured NuGet package wasn't available in the source:

Installing pack Microsoft.Maui.Core.Ref.android version 6.0.100-preview.7.1063+sha.f5acc965e-azdo.5006556...
Rolling back pack Microsoft.Maui.Core.Ref.android installation...
Workload repair failed: microsoft.maui.core.ref.android::6.0.100-preview.7.1063 is not found in NuGet feeds https://api.nuget.org/v3/index.json;https://pkgs.dev.azure.com/dnceng/public/_packaging/6.0.100-preview.7.21379.14-shipping-1/nuget/v3/index.json".

I can see that the current version of the 'missing' package is "Microsoft.Maui.Core.Ref.android -Version 6.0.100-preview.7.1345" from three days ago when preview 7 was released.

Upon further investigation this doesn't appear to be a maui-check issue. Trying to install the maui workloads manually using dotnet workload install maui results in the same error:

Workload installation failed: The JSON value could not be converted to Microsoft.NET.Sdk.WorkloadManifestReader.WorkloadPackId. Path: $.Id | LineNumber: 0 | BytePositionInLine: 52.

Aaaaaaaaaaaaaaaaaaaaaaaaad.......

In more recent developments, it appears that there was a manifest change a while ago in some of the json configs, so this issue is likely to occur when you have previously had Preview 6 installed.

The recommended fix is to manually delete everything under "C:\Program Files\dotnet\metadata\workloads" and then install the workloads manually followed by another run at maui-check:

dotnet workload install maui

then

maui-check

Worked for me:

[davidbuckleyni]

@Redth might be one for u to look above as to a fix for future releases

Probally still be worth redth checking the json change and asking users to delete workloads to update?

dotnet tool update -g redth.net.maui.check

should do the trick (had the same problem)

[johncclayton]

I also had an older preview of 6.0 installed and encountered the same errors with both maui-check and the dotnet workload install maui commands.

+1 on the fix, https://github.com/Redth/dotnet-maui-check/issues/105#issuecomment-898295227

[MartyIX]

This helped me to install preview7 after having installed preview6:

dotnet workload install maui -v d --ignore-failed-sources --disable-parallel --temp-dir="C:\maui-temp"

[davidbuckleyni]

@Redth buddy u could easily add remove preview versions before installing maybe would be a good option are u accepting pull request into the product.

[cheles]

I still get this with Tool 'redth.net.maui.check' was reinstalled with the latest stable version (version '0.8.4').

Workload installation failed: One or more errors occurred. (microsoft.maui.core.ref.android.msi.x64::6.0.100-rc.1.1351 is not found in NuGet feeds https://api.nuget.org/v3/index.json;C:\Program Files (x86)\Microsoft SDKs\NuGetPackages".)

maui-check --preview did the trick and installed all req workloads

[arivoir]

The recommended fix is to manually delete everything under "C:\Program Files\dotnet\metadata\workloads" and then install the workloads manually followed by another run at maui-check:

Where are the workloads installed on macos?

[arivoir]

FYI I found it here /usr/local/share/dotnet/metadata/workloads

[AraHaan]

Another thing that makes me upset about this tool is that if you say are using the rc.2 .NET SDK and do the steps above to properly install the RC.2 versions of MAUI, this tool then forces the uninstall of the RC.2 versions for the preview 7 ones which makes me mad because I want to keep those versions and use it with Visual Studio.

Honestly I think the tool should check for Preview 7 (or newer) and if they have a version newer than Preview 7 installed (like rc.1 or rc.2) to use that to install maui (or the templates to maui) on.

[drinck]

This helped me. I wanted to add my symptoms:

Messing around and updating from VS2022 Preview 3 to Preview 4, MAUI templates were missing when I went to create a new project. I tried maui-check (which Microsoft says is not necessary), but that would error on workloads: maui, maui-ios, maui-android, maui-catalyst. I would see this error:

[sencagri]

Same here

[jingliancui]

That's work for me if I want to use the maui preview8.

1. Clean the history data use this script: https://github.com/Redth/dotnet-maui-check/blob/main/Clean-Old-DotNet6-Previews.ps1

2.Delete the maui-check tool: dotnet tool uninstall -g Redth.Net.Maui.Check

3.Uninstall VS2012 Preview4

4.Reinstall VS2012 Preview4

5.Reinstall maui-check tool: dotnet tool install -g Redth.Net.Maui.Check

6.Do check script: maui-check

[uzairali001]

Just run this script https://github.com/Redth/dotnet-maui-check/blob/main/Clean-Old-DotNet6-Previews.ps1 then dotnet tool update -g Redth.Net.Maui.Check then maui-check

These should be steps done by maui check user should not need to do all this @Redth
