    the anydesk repositories are signed with an outdated key. They should have provided an updated key, and if they continue to not provide an updated key for you to add to your system, then you are going to have to contact AnyDesk for support - it's their software repository so it's not really something we can fix if they haven't provided an updated key Commented Dec 23, 2021 at 18:20

You have to follow their documentation from http://deb.anydesk.com/howto.html .

To (re)add GPG key open terminal and execute:

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

then update package lists by

sudo apt-get update

The documentation in anydesk/howto.html is outdated if you are using Debian 12. As you can read in man 8 apt-key

apt-key(8) will last be available in Debian 11 and Ubuntu 22.04

So, I wrote a simple bash script to install anydesk in Debian Bookworm from repository:

#!/bin/bash

wget -O- https://keys.anydesk.com/repos/DEB-GPG-KEY | gpg --dearmor | tee /etc/apt/keyrings/anydesk.gpg > /dev/null

echo deb [signed-by=/etc/apt/keyrings/anydesk.gpg] http://deb.anydesk.com/ all main | tee /etc/apt/sources.list.d/anydesk-stable.list

apt update && apt -y install anydesk

  • It is advisable to use /usr/share/keyrings/ instead of /etc/apt/keyrings/ for third party repositories. wiki.debian.org/DebianRepository/UseThirdParty Also the tee commands will need to be run with sudo. Commented Dec 20, 2023 at 10:41
