Question

Folks I started getting this error in a Github Action late yesterday ```Diagnostics 199 pulumi pulumi Stack grv api resources grv api dev 200 You must install or update NET to run this application 201 App home runner work GeneralRV API GeneralRV API Devops azure environment pulumi grv api resources bin Debug netcoreapp3 1 grv api resources 202 Architecture x64 203 Framework <http Microsoft NETCore App|Microsoft NETCore App> version 3 1 0 x64 204 NET location usr share dotnet 205 The following frameworks were found 206 6 0 11 at usr share dotnet shared Microsoft NETCore App 207 7 0 0 at usr share dotnet shared Microsoft NETCore App ``` Nothing about the action s dependence on net core has changed since last week when it worked I ll be looking into it shortly but I thought someone here might be able to short circuit my need to research Is it possibly something as straightforward as a uses step within the job to explicitly reference a version of net core

Are you using dotnetcore3 1 The runners might not have it anymore and you may need to explicitly install it

little-library-54601 · Answer

To my knowledge I m not explicitly using it I don t have it installed locally and the pulumi commands work locally

bored-activity-40468 · Answer

Local you can see by dotnet list runtimes

bored-activity-40468 · Answer

What version is referenced in the csproj

bored-activity-40468 · Answer

it looks like 3 1 ` home runner work GeneralRV API GeneralRV API Devops azure environment pulumi grv api resources bin Debug netcoreapp3 1 grv api resource`

bored-activity-40468 · Answer

probably need to update that version or add ``` uses actions setup dotnet v3 with dotnet version 3 1 x ```

bored-activity-40468 · Answer

The runners should still have 3 1 4 though

strange

little-library-54601 · Answer

I guess my question is why that wouldn t work Is there something about pulumi that demands net core 3 1 x

little-library-54601 · Answer

And if so why don t I see the problem locally

clever-sunset-76585 · Answer

You probably have 3 1 runtime installed locally What was the output of running the command < bored activity 40468> mentioned Also see the net 6 support announcement blog post from Pulumi It seems that the cloud provider packages and the core Pulumi SDK are still targeting the 3 1 runtime for backwards compatibility

little-library-54601 · Answer

I do have 3 1 installed locally I had been looking at installed sdks

icy-doctor-13719 · Answer

i use ``` uses actions setup dotnet v1 with dotnet version 6 x``` in GH actions with no issue

little-library-54601 · Answer

Yeah I already had that for building my app just not for the Pulumi job And no errors until today

icy-doctor-13719 · Answer

little-library-54601 · Answer
