When trying to update the software on the edge computer 752-9800 with apt update command, you will get an Err 5 not found … error. This is because of our expired docker GPG key. I wasn’t able to fix the broken certs, so I just uninstalled docker and re-install docker using these commands. If someone knows the command to update the key please post it!
These were done when logged into cockpit WBM with root account. If you do this with ssh using edge user, then you will need to add sudo to these commands.
(User docker to remove all containers, images and volumes if you’ve created any.)
apt purge -y docker docker.io wmdocker cockpit-docker apt autoremove -y --purge docker docker.io wmdocker cockpit-docker
Now you can reinstall docker:
apt-get update apt-get install apt-transport-https ca-certificates curl gnupg2 software-properties-common curl -fsSL https://download.docker.com/linux/debian/gpg | sudo apt-key add - add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/debian buster stable" apt-get update apt-get install docker-ce docker-ce-cli containerd.io docker -v
