Ubuntu 22.04 - apt-key is deprecated. Manage keyring files in trusted.gpg.d instead

[edwinhamers]

Describe the bug When following the install guide for Ubuntu (https://packages.cisofy.com/community/#debian-ubuntu) the public key is added using apt-key. But apt-key will display deprecation warnings. Can the docs be updated to include a working method for using gpg on Ubuntu 22.04 LTS

Version

• Distribution Ubuntu 22.04 TLS
• Lynis version (latest)

See https://wiki.debian.org/DebianRepository/UseThirdParty, e.g

echo "deb [signed-by=/usr/share/keyrings/keys/cisofy-software-public.gpg] https://packages.cisofy.com/community/lynis/deb/ stable main" | sudo tee /etc/apt/sources.list.d/cisofy-lynis.list

Here is a solution

wget -O - https://packages.cisofy.com/keys/cisofy-software-public.key|sudo gpg --dearmour -o /usr/share/keyrings/lynis.gpg

And echo "deb [signed-by=/usr/share/keyrings/keys/lynis.gpg] https://packages.cisofy.com/community/lynis/deb/ stable main" | sudo tee /etc/apt/sources.list.d/cisofy-lynis.list

This is what worked for me:

curl -fsSL https://packages.cisofy.com/keys/cisofy-software-public.key | sudo gpg --dearmor -o /usr/share/keyrings/lynis.gpg

echo "deb [signed-by=/usr/share/keyrings/lynis.gpg] https://packages.cisofy.com/community/lynis/deb/ stable main" | sudo tee /etc/apt/sources.list.d/cisofy-lynis.list
