# Calibre 3.29 requires this approach, to overcome error:
#
#    calibre-bin : Depends: qtbase-abi-5-10-0 but it is not installable
#   E: Unable to correct problems, you have held broken packages.
#
# Above error proved insurmountable when trying most all scripts in /opt/iiab/iiab/scripts -- even those that DID solve this error:
#
#    calibre : Depends: python-pyqt5 (>= 5.11.2+dfsg-1+b1)

# Thanks to Jerry Vonau (https://github.com/jvonau) who made this critical
# breakthrough possible!
