How to add the APT key for Microsoft packages
Never mind, the error message was kind of misleading.
The problem was that my sources.list file (that I had taken from Microsoft's own instructions) was pointing to a non-existent key file:
deb [arch=amd64 signed-by=/usr/share/keyrings/packages.microsoft.gpg] https://packages.microsoft.com/repos/vscode stable main
I removed the signed-by
option from the square brackets, and everything worked.

I'm trying to install some packages from the Microsoft APT Repository (because I hate Snap with a passion!) but I can't seem to be able to add its key:
$ curl https://packages.microsoft.com/keys/microsoft.asc | sudo apt-key add - OK
It says OK, but the key doesn't work:
$ sudo apt update [...] Err:7 https://packages.microsoft.com/repos/vscode stable InRelease The following signatures couldn't be verified because the public key is not available: NO_PUBKEY EB3E94ADBE1229CF Reading package lists... Done W: GPG error: https://packages.microsoft.com/repos/vscode stable InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY EB3E94ADBE1229CF E: The repository 'https://packages.microsoft.com/repos/vscode stable 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.
I also tried retrieving the key starting from the NO_PUBKEY id printed by apt-get:
$ sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv EB3E94ADBE1229CF Executing: /tmp/apt-key-gpghome.q9IjlmqKv9/gpg.1.sh --keyserver hkp://keyserver.ubuntu.com:80 --recv EB3E94ADBE1229CF gpg: key EB3E94ADBE1229CF: "Microsoft (Release signing) <[email protected]>" not changed gpg: Total number processed: 1 gpg: unchanged: 1
It says "not changed" and in fact, nothing changes.
If I check the output of
apt-key list
I see that all third-party keys have asub rsa4096
except Microsoft's. Is this why it doesn't work?$ sudo apt-key list /etc/apt/trusted.gpg -------------------- pub rsa4096 2017-05-08 [SCEA] 1EDD E2CD FC02 5D17 F6DA 9EC0 ADAE 6AD2 8A8F 901A uid [ unknown] Sublime HQ Pty Ltd <[email protected]> sub rsa4096 2017-05-08 [S] pub rsa4096 2016-04-12 [SC] EB4C 1BFD 4F04 2F6D DDCC EC91 7721 F63B D38B 4796 uid [ unknown] Google Inc.
