# Caveat: calibre-install-latest-rpi.sh worked up to Calibre 3.23 in May 2018,
# but fails to "apt install" Calibre 3.24+ in June 2018:
#
#   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
#   E: Unable to correct problems, you have held broken packages.

# So the new recipe (2018-06-18) for RPi is:
#
# 1. "apt install calibre calibre-bin" (2.75.1, part of Raspbian OS)
#
# 2. calibre-install-packages.sh installs those packages that
# calibre-install-latest-rpi.sh used to install for Calibre 3.23:
#
#   https://github.com/iiab/iiab/pull/839
#
# 3. calibre-install-latest.sh installs Debian's own calibre & calibre-bin etc:
#
#   https://github.com/iiab/iiab/pull/833    # WORKED ON RPI 3 AND RPI 3 B+
#   https://github.com/iiab/iiab/issues/835  # FAILED ON RPI ZERO W, DUE TO INSTALLING libc6 (IF ABOVE STEP 2 NOT RUN!)

# FYI Calibre 3.25 (and early signs of 3.26) are the latest available from
# testing as of 2018-06-18:
#
#   http://raspbian.raspberrypi.org/raspbian/pool/main/c/calibre/
#   http://archive.raspbian.org/raspbian/pool/main/c/calibre/
#   https://packages.debian.org/search?keywords=calibre
#   http://deb.debian.org/debian/pool/main/c/calibre/
#
# Might break future updates; you have been warned.
