Kernel immediately ends on Pop_OS

[calebjacobo]

I'm on Pop_OS and I cannot run .NET Interactive Notebooks. When I try to create a new notebook, the kernel will start and then immediately end.

I did a fresh install of the OS, then I installed the dotnet SDK, VS Code, and the .Net Interactive Notebook extension, and that's it. I try to create a new blank notebook and the server starts, then stops with an error. I'm pasting that console output below:

`Starting kernel for 'untitled:Untitled-1.dib?dotnet-interactive' using: dotnet tool run dotnet-interactive -- [vscode] stdio --working-dir /home/calebjacobo/Downloads

Is this a permissions thing? I tried the same thing on my MacBook and when I created the notebook, it asked me for permission to access the downloads folder. Is this simply a matter of granting the right permissions, and if so, how?

[jonsequitur]

I don't know. That's possible.

Another possibility is that the TFM isn't supported by the System.Management.Automation (aka PowerShell) package. If you create a simple console app referencing this package, instantiate some type from it, and build and run it, do you see a similar error?

[calebjacobo]

@jonsequitur sorry, I’m unsure how to do this.

[calebjacobo]

@jonsequitur

Ok, I made a simple console app, then tried to print out something from System.Management.Automation and I got the same kind of error:

`Unhandled exception. System.IO.FileNotFoundException: Could not load file or assembly 'System.Management.Automation, Version=7.2.6.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'. The system cannot find the file specified.

File name: 'System.Management.Automation, Version=7.2.6.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'`

So it seems like your assumption could be correct. What is the TFM?

[jonsequitur]

TFM is the target framework moniker. Assemblies are often found inside TFM-specific subfolders in a NuGet package and I'm guessing from the outcome of your experiment that on Pop_OS it's looking for a TFM-specific subfolder which doesn't exist. (The only one I see is net6.0)

@daxian-dbw Any insights here?

[daxian-dbw]

No, no idea what was happening. The 7.2.6 version of PowerShell SDK targets net6.0, and dotnet-interactive should've bundled everything already.

I'm also experiencing this on Pop!_OS

I tried to see if I could capture where it's looking (when running dotnet-interactive stdio for example) as the exception message doesn't provide much more detail.

inotifywatch -r /home/sadbooth/.nuget

Not very useful 🤷

Here's the file tree for that path:

Then I tried running the same command with strace - log

I'm also seeing this on PopOS when trying to use dotnet interactive or the Polyglot Notebooks plugin in VS Code.

getting same issue in Calculate Linux, a distributive based on Gentoo

dotnet can be installed here by two packages:

• dev-dotnet/dotnet-sdk-bin - binary package - a dotnet binary is downloaded and installed
• dev-dotnet/dotnet-sdk - dotnet is build from sources

The issue is reproducable only with package dev-dotnet/dotnet-sdk, e.g. building dotnet from sources

[obratim]

It is an issue in Microsoft.PowerShell.SDK package.

System.Management.Automation is stored in same git repository and is referenced as project, not as a package. As the result in the nuspec file written that it depends on a one version of System.Management.Automation, but inside nupkg archive under ref/net8.0/ there is another version of System.Management.Automation.dll.

This confusion causes error.
