I was attempting to install Signal using a helpful guide by @Sven originally posted here:
However, when attempting to download the signing key for the package, I got the following error:
Warning: apt-key is depreciated. Manage keyring files in trusted.gpg.d instead (see apt-key(8)).
The same issue has come up with several other attempts to install packages and I have either used less secure methods to install or opted for different software.
I have looked for solutions (more than I care to admit) but had no success. Can someone post a working example of the commands required to install Signal in the above context? I’m not using apt-cache-ng so just a standard example is all I need. Hopefully that should also be enough to help me with other depreciated package installation guides.
