Since release of Debian stable release codenamed „bookworm“ up until today the distribution is not officially supported by the Estonian governments official installation script of their mandatory digital ID software. You would think Debian’s usually longer release cylce would make it easier to catch up with software releases, but here we go again.
Fortunately, installation in the new distribution is a bit more straightforward than before. The whole installation following this instruction might be done in 5-10 minutes.
Given that we have a fresh installation in front of us, we first import the signing key to the repository.
wget -qO- https://installer.id.ee/media/install-scripts/C6C83D68.pub | sudo tee /etc/apt/keyrings/open-eid.asc
Then add the official open-eid repository.
sudo tee -a /etc/apt/sources.list.d/open-eid.list <<< '# open-eid Estonian ID-Card'
sudo tee -a /etc/apt/sources.list.d/open-eid.list <<< 'deb [signed-by=/etc/apt/keyrings/open-eid.asc] https://installer.id.ee/media/ubuntu/ jammy main'
Install required packages. Feel free to leave out the part installing firefox or chrome package, depending on whichever browser you are using or not using.
sudo apt update
sudo apt install open-eid web-eid-firefox web-eid-chrome
Check if a new application „Digidoc“ is installed. Then open your browser of choice and open your add-ons preference dialog to see if web-eid is installed and enabled. After that you are good to go!
