I was recommended to use the official instructions for Debian, but substitute the corresponding Debian codename here
```
sudo tee /etc/apt/sources.list.d/docker.sources <<EOF
Types: deb
URIs: https://download.docker.com/linux/debian
Suites: $(. /etc/os-release && echo "$VERSION_CODENAME")
Components: stable
Architectures: $(dpkg --print-architecture)
Signed-By: /etc/apt/keyrings/docker.asc
EOF
```
for `Suites`. Curiously they suggested using `Suites: trixie` even for Devuan freia. Works so far
