I just installed Calibre for ebook management via apt-get on Ubuntu 10.04, however I found out that it's one major version behind the current release, so I decided to reinstall it directly from sources.
When I uninstalled the packaged version, apt added bunch of dependencies to the autoremove queue, and as I installed newer version of Calibre from sources, it has no knowledge of it being dependent on those packages.
Now I basically have all libraries that I want, but they are still in the autoremove queue.
The following packages were automatically installed and are no longer required: libqt4-script libqt4-designer libqt4-dbus python-lxml python-cherrypy3 python-encutils libqt4-xmlpatterns libqt4-help python-qt4 python-clientform python-sip python-django python-mechanize libqt4-svg python-django-tagging libphonon4 libqt4-xml libqt4-assistant libqt4-webkit libqt4-scripttools python-beautifulsoup python-pypdf python-dateutil python-cssutils Use 'apt-get autoremove' to remove them.
How do I tell apt that I want to keep these packages installed, without reinstalling them manually?
