for reasons XYZ, I would prefer to install easy-installer package via apt subsystem. Snap is currently broken on my Ubuntu 20.x LTE and upgrade to next LTE causes other trouble. So I would prefer rather to install in normal way for apt system. Or at least with dpkg from single .deb file (I can install dependencies manually).
Please note that I didn’t update the Debian package after June. New devices were added in the newer versions (e.g. the Fairphone 4). These are not yet included in the unofficial Debian package.
