I deleted Skype and I got error.
So I followed answers here and I messed up badly apt-key deprecation warning when updating system
My keyring:
/etc/apt/trusted.gpg.d/microsoft.gpg
------------------------------------
pub rsa2048 2015-10-28 [SC]
BC52 8686 B50D 79E3 39D3 721C EB3E 94AD BE12 29CF
uid [ unknown] Microsoft (Release signing) <[email protected]>
Following answers, I get to this step:
deb [arch=amd64 signed-by=/usr/share/keyrings/microsoft.gpg] https://packages.microsoft.com/repos/edge/ stable main
So I got problems here. Like there is no deb command.
So I did:
sudo apt-key del BE1229CF
pc@pc:~$ sudo apt-get update
[sudo] password for pc:
