Clearsigned file isn't valid, got 'NOSPLIT' (does the network require authentication?)

[acidprime]

Unable to install vscode in Ubuntu 18.04 , trying locally in vagrant and on a remote GCP node. Same error which makes me think something is wrong with the remote repo configuration. Two different internet connections and DNS servers in other words.

Notice: /Stage[main]/Apt::Update/Exec[apt_update]/returns: E: Failed to fetch https://packages.microsoft.com/repos/vscode/dists/stable/InRelease Clearsigned file isn't valid, got 'NOSPLIT' (does the network require authentication?)

apt source

deb https://packages.microsoft.com/repos/vscode stable main

Ubuntu 18.04

This has worked hundreds of times in the last 6 months and just started failing today.

I'm using key BC528686B50D79E339D3721CEB3E94ADBE1229CF which seems to the correct one as of today

wget -qO- https://packages.microsoft.com/keys/microsoft.asc | gpg --show-keys
pub   rsa2048 2015-10-28 [SC]
      BC528686B50D79E339D3721CEB3E94ADBE1229CF
uid                      Microsoft (Release signing) <gpgsecurity@microsoft.com>

Managing this puppet as so

  apt::source { 'vscode':
    comment  => 'This is the official VSCode repository',
    location => 'https://packages.microsoft.com/repos/vscode',
    release  => 'stable',
    repos    => 'main',
    key      => {
        'id'     => 'BC528686B50D79E339D3721CEB3E94ADBE1229CF',
        'server' => 'keyserver.ubuntu.com',
    },
    include  => {
      'deb' => true,
    },
  }

Found similiar issue , so this has happened in the past I believe

I'm having the same issue, Ubuntu 20.04:

$ sudo apt update
...
E: Failed to fetch https://packages.microsoft.com/repos/vscode/dists/stable/InRelease  Clearsigned file isn't valid, got 'NOSPLIT' (does the network require authentication?)
E: The repository 'https://packages.microsoft.com/repos/vscode stable InRelease' is no longer signed.
