Properly add 3rd party app repo to apt source list

When you try installing packages from third-party repositories on recent Ubuntu you will be seeing a warning message about 'apt-key being deprecated'. This article is to share how to properly add 3rd party package report into apt source list.

The installation steps recommended by AnyDesk page says:

- add repository key to Trusted software providers list

wget -qO - https://keys.anydesk.com/repos/DEB-GPG-KEY | apt-key add -

- add the repository:

echo "deb http://deb.anydesk.com/ all main" > /etc/apt/sources.list.d/anydesk-stable.list

- update apt cache:

apt update

- install anydesk:

apt install anydesk

The new way of adding 3rd party report should be:

- add anydesk repo key to keyrings folder

wget -q0 -  https://keys.anydesk.com/repos/DEB-GPG-KEY | gpg --dearmor | sudo tee /usr/share/keyrings/anydesk.gpg

- add anydesk source list to folder

echo "deb [signed-by=/usr/share/keyrings/anydesk.gpg] http://deb.anydesk.com/ all main" | sudo tee /etc/apt/source.list.d/anydesk.list
