Hello,
to install signal desktop client, I followed their instructions, which
is to add their repository and, obviously their Kry.
However, I got a warning
Warning: apt-key is deprecated. Manage keyring files in trusted.gpg.d
instead (see apt-key(8)).
But how to do this ?
man apt-key says :
Note: Instead of using this command a keyring should be placed directly
in the /etc/apt/trusted.gpg.d/ directory with a descriptive name and
either "gpg" or "asc" as file extension.
So the question is how can I get a keyring file from the key file I
downloaded ?
