Howto use the new keystore

If you get a message like this, you imported you apt key in the old keystore, since apt-key is deprecated.

Schlüssel ist im veralteten Schlüsselbund trusted.gpg gespeichert (/etc/apt/trusted.gpg), siehe den Abschnitt MISSBILLIGUNG in apt-key(8) für Details.

If you did something like this:

wget https://beispiel.de/key/repo-key.gpg | apt-key add -

The new way of adding key to keystore is with gpg:

wget -O- <https://beispiel.de/key/repo-key.gpg> | gpg --dearmor | sudo tee /usr/share/keyrings/<meinresporitoy>-archive-keyring.gpg

To clean everything up search for the key:

apt-key list

.
.
pub   rsa2048 2015-10-28 [SC]
      BC52 8686 B50D 79E3 39D3  721C EB3E 94AD BE12 29CF
uid        [ unbekannt] Microsoft (Release signing) <gpgsecurity@microsoft.com>
.
.
.

and the delete the old key with the fingerpring (last 8 signs)

apt-key del BE1229CF

And now the super easy way for those who read to the end :)

apt-key export BE1229CF | sudo gpg --dearmour -o /usr/share/keyrings/microsoft_keyring.gpg

apt-key del BE1229CF

Now add a tag in the source.list in front of the url:

deb [arch=amd64 signed-by=/usr/share/keyrings/microsoft_keyring] https://packages.microsoft.com/repos/edge stable main
sudo apt update

And everything is clean now!
