On WSL Ubuntu 18.04 dotnet tool install -g Cake.Tool and Octopus.DotNet.Cli fails

The combination of WSL and Ubuntu 18.04 seems to cause issues with .NET global tools.

Steps to reproduce

dotnet tool install -g Cake.Tool

dotnet tool install -g Octopus.DotNet.Cli

Expected behavior

+ You can invoke the tool using the following command: dotnet-cake
+ Tool 'cake.tool' (version '0.30.0') was successfully installed.

+ You can invoke the tool using the following command: dotnet-octo
+ Tool 'octopus.dotnet.cli' (version '4.41.0') was successfully installed.

Actual behavior

- The settings file in the tool's NuGet package is invalid: Settings file 'DotnetToolSettings.xml' was not found in the package.
- Tool 'cake.tool' failed to install. Please contact the tool author for assistance.

- The settings file in the tool's NuGet package is invalid: Settings file 'DotnetToolSettings.xml' was not found in the package.
- Tool 'octopus.dotnet.cli' failed to install. Please contact the tool author for assistance.

I’ve successfully installed Cake.Tool and Octopus.DotNet.Cli using 2.1.401 on

• Docker
  • microsoft/dotnet:2.1-sdk
  • ubuntu:18.04
  • ubuntu:16.04
  • fedora:28
  • centos:centos7
• WSL
  • Ubuntu 16.04
  • openSuse Leap 42
  • Debian 9
• Windows
• Mac

So doesn’t seem package related but rather a specific environment issue.

We are seeing a very similar issue here: https://github.com/NuKeeperDotNet/NuKeeper/issues/433

Install on Ubuntu 18.04 fails, This is for both Ubuntu hosted on WSL or on a cloud VM. Error is:

The settings file in the tool’s NuGet package is invalid: Settings file ‘DotnetToolSettings.xml’ was not found in the package.

The error is not correct, that file exists. This might be a capitalisation issue - the tool name is “NuKeeper”. Or it might be due to package signing failing.

We are considering changing the tool name caps to “nukeeper” is it is confirmed that this is necessary for Linux support. But we can’t tell the cause since the error message is false. The docs on NETCore global tools don’t say anything about naming requirements for use in Linux. Are there any, particularly with regard to capitalisation?
