Powershell: Failures on command-line for .NET Core SDK install for Ubuntu 16.04

[rkeithhill]

I'm trying to install .NET Core SDK following these instructions for Ubuntu 16.04 from PowerShell Core and it is not working.

Steps to reproduce

1. curl https://packages.microsoft.com/keys/microsoft.asc | gpg --dearmor > microsoft.gpg

2. sudo sh -c 'echo "deb [arch=amd64] https://packages.microsoft.com/repos/microsoft-ubuntu-xenial-prod xenial main" > /etc/apt/sources.list.d/dotnetdev.list'

Expected behavior

1. Outputs a utf8 file without BOM.

2. Works.

Actual behavior

1. Outputs file WITH BOM which causes an error later:

I thought by now (RC-2) we were defaulting to utf8 no BOM on Linux?

1. Does not create the dotnetdev.list file. Instead, outputs "deb" and does nothing else.

The root of the problem is likely quoting - again...

sh -c 'echo "deb [arch=amd64] https://packages.microsoft.com/repos/microsoft-ubuntu-xenial-prod xenial main"'

Echos just:

deb

Partially from: https://github.com/Microsoft/vscode/issues/27970

curl https://packages.microsoft.com/keys/microsoft.asc | gpg --dearmor > microsoft.gpg
sudo mv microsoft.gpg /etc/apt/trusted.gpg.d/microsoft.gpg

It worked for me, when it failed on LSW.

Idk the security implications of this. No idea why this public key is not already added to begin with.

@rkeithhill Do you see the issue with PowerShell 7.0?
