libdvd-pkg ---------- `dpkg-reconfigure libdvd-pkg` may be used to build and install libdvdcss* package(s). Generated "libdvdcss*" packages will be saved to "/usr/src/libdvd-pkg" (but deleted on purge of "libdvd-pkg"). APT post-invoke handler (hook) can perform automatic upgrades of guest package(s) on host package upgrade. After end of batch of APT operations hook checks whether guest package(s) can be updated. If upgrade detected then hook will attempt to download/build and install package(s) using `dpkg -i` but only if `apt-get check` reported no errors. Although at the moment there are no known problems associated with APT post-invoke hook it may be considered unsafe by some people due to its potential to interfere with APT/dpkg operations. Use at your own risk. ## Preparing for offline build If automatic attempt to download source archive failed (due to connectivity issues etc.) then source archive can be manually downloaded from http://download.videolan.org/pub/libdvdcss/ and placed to "/usr/src/libdvd-pkg". However it is important to make sure that archive version matches the current package version and that the file is properly (re-)named. For example "libdvdcss-1.2.13.tar.bz2" should be saved as /usr/src/libdvd-pkg/libdvdcss_1.2.13.orig.tar.bz2
