Package: calibre Version: 4.99.4+dfsg+really4.10.0+py3-2 Severity: normal I have calibre installed on two Debian systems. My Kindle Paperwhite was only being detected on one of them. I used calibre's "debug device detection" to discover that it was trying to use a Python udisks function and failing. The system where it worked already had udisks2 installed. Once I installed udisks2 on the other system, it worked too.
I think udisks2 (or an underlying library?) should be a Depends, or at least Recommended. -- System Information: Debian Release: bullseye/sid APT prefers testing APT policy: (500, 'testing'), (400, 'unstable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 5.4.0-4-amd64 (SMP w/8 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) Versions of packages calibre depends on: ii calibre-bin 4.99.4+dfsg+really4.10.0+py3-2 ii dpkg 1.19.7 ii fonts-liberation 1:1.07.4-11 ii imagemagick 8:6.9.10.23+dfsg-2.1+b2 ii imagemagick-6.q16 [imagemagick] 8:6.9.10.23+dfsg-2.1+b2 ii libjpeg-turbo-progs 1:1.5.2-2+b1 ii libjs-mathjax 2.7.4+dfsg-1 ii libjxr-tools 1.1-6+b1 ii optipng 0.7.7-1+b1 ii poppler-utils 0.71.0-6 ii python3 3.7.5-3 ii python3-apsw 3.30.1-r1-1.1 ii python3-bs4 4.8.2-1 ii python3-chardet 3.0.4-4 ii python3-chm 0.8.6-2 ii python3-css-parser 1.0.4-2 ii python3-cssselect 1.1.0-2 ii python3-cssutils 1.0.2-3 ii python3-dateutil 2.7.3-3 ii python3-dbus 1.2.16-1 ii python3-feedparser 5.2.1-2 ii python3-html2text 2020.1.16-1 ii python3-html5-parser 0.4.9-3 ii python3-html5lib 1.0.1-2 ii python3-lxml 4.5.0-1 ii python3-markdown 3.1.1-2 ii python3-mechanize 1:0.4.5-2 ii python3-msgpack 0.5.6-3 ii python3-netifaces 0.10.9-0.2 ii python3-pil 6.2.1-2+b1 ii python3-pkg-resources 44.0.0-1 ii python3-pygments 2.3.1+dfsg-1 ii python3-pyparsing 2.4.6-1 ii python3-pyqt5 5.14.1+dfsg-3 ii python3-pyqt5.qtsvg 5.14.1+dfsg-3 ii python3-pyqt5.qtwebengine 5.14.0-2 ii python3-regex 0.1.20190819-2 ii python3-routes 2.4.1-2 ii python3-zeroconf 0.23.0-1 ii xdg-utils 1.1.3-1 Versions of packages calibre recommends: pn python3-dnspython <none> Versions of packages calibre suggests: pn python3-unrardll <none> -- no debconf information
