Unable to install az on Ubuntu 18.04 w apt

Describe the bug Unable to install a Microsoft signing key for az which works on Ubuntu 18.04 bionic and consequentially unable to install az via apt.

To Reproduce Follow instructions in the document: https://docs.microsoft.com/en-us/cli/azure/install-azure-cli-apt?view=azure-cli-latest

sudo apt-key adv --keyserver packages.microsoft.com --recv-keys 52E16F86FEE04B979B07E28DB02C46DF417A0893
Executing: /tmp/apt-key-gpghome.8anL89cvRR/gpg.1.sh --keyserver packages.microsoft.com --recv-keys 52E16F86FEE04B979B07E28DB02C46DF417A0893
gpg: connecting dirmngr at '/tmp/apt-key-gpghome.8anL89cvRR/S.dirmngr' failed: IPC connect call failed
gpg: keyserver receive failed: No dirmngr

The new signing key installs properly (curl -L https://packages.microsoft.com/keys/microsoft.asc | sudo apt-key add -, but this key still doesn’t allow me to download from the apt source.

sudo apt-key list
...
pub   rsa2048 2015-10-28 [SC]
      BC52 8686 B50D 79E3 39D3  721C EB3E 94AD BE12 29CF
uid           [ unknown] Microsoft (Release signing) <[e-mail]>

Then this is the error when doing the sudo apt-get update

Err:4 https://packages.microsoft.com/repos/azure-cli bionic InRelease
  The following signatures couldn't be verified because the public key is not available: NO_PUBKEY B02C46DF417A0893
Reading package lists... Done
W: GPG error: https://packages.microsoft.com/repos/azure-cli bionic InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY B02C46DF417A0893
E: The repository 'https://packages.microsoft.com/repos/azure-cli bionic InRelease' is not signed.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.

Expected behavior Either the old or new signing key allows me to sudo apt-get update from the az apt source.

Environment summary Bash on Windows with 18.04 (bionic) LTS

Additional context lsb-release and dirmngr are installed and the latest versions.

I have the same issue. Running Ubuntu 18.04 from the Windows store via Windows subsystem for Linux.

Thank you for reporting this issue. We’re aware of it now. We’re in the process of switching the old repository key to a new one. I will post back when the process is done.
