Error on running script (unable to restore packages)

[hitochan777]

Problem

When I run a script file with the following command I get an error as shown below:

$ dotnet script foo.csx
Unable to restore packages from '/home/myuser/.cache/dotnet-script/home/myuser/developer/net5.0/script.csproj'
Make sure that all script files contains valid NuGet references

Details:
/home/myuser/.cache/dotnet-script/home/myuser/developer/net5.0 : dotnet restore "/home/myuser/.cache/dotnet-script/home/myuser/developer/net5.0/script.csproj" -r linux-x64  --configfile "/home/myuser/.nuget/NuGet/NuGet.Config"

The content of the script is as follows:

$ cat foo.csx                                       
Console.WriteLine("hello");

.NET runtimes installed:

To install additional .NET runtimes or SDKs:
  https://aka.ms/dotnet-download

$ dotnet script --version
1.0.1

I am wondering if upgrading .NET Core from 3.x to 5.x and dotnet-script from 0.50.1 to 1.0.1 is somewhat related.
#199 seems relevant but what is different from the issue is that I do not import any packages.

did you try running with --no-cache?

also it might be good to try uninstalling the tool and reinstalling again

@filipw

Thank you for your reply.
I tried both but none of them is working.
Is it possible that dotnet-script is not compatible with .NET installed via snap?

Hmm I don't know why but I was able to run scripts after reinstalling .NET via apt-get install instead of snap.
Installation via snap seems to cause other issues such as being unable to run vscode-omnisharp extension...
Anyways thanks for the help! @filipw
