Suddenly with Calibre 3.26.0 (from http://raspbian.raspberrypi.org/rasp...ain/c/calibre/) our trusted installation recipe for Calibre 3.x on Rapberry Pi (from 2017) once again now works:

echo "deb http://raspbian.raspberrypi.org/raspbian/ testing main" > /etc/apt/sources.list.d/rpi-testing.list
apt update
apt -y install calibre calibre-bin

Does anybody know what exactly caused Calibre 3.24 and 3.25 to fail on Raspbian (on Raspberry Pi) over the past 3 weeks, to help everyone avoid a recurrence of this very painful pattern? (Affecting many developing world schools!)

With a HUGE Thank You to whoever is the anonymous heroic person who stepped in to fix the error below:

The following packages have unmet dependencies:
calibre : Depends: python-pyqt5 (>= 5.10.1+dfsg-2) but 5.10.1+dfsg-1+rpi1 is to be installed
