Here is one way.
To identify packages that are no longer present in the archive
% apt-show-versions -r . | grep "No available version in archive"
| cut -f 1 -d ':' | sort | uniq > ~/x/cruft.txt
To identify packages that are no longer present in the archive and
contain the word lib in their names
% apt-show-versions -r lib | grep "No available version in
archive" | cut -f 1 -d ':' | sort | uniq > ~/x/cruft.txt
You need to sort uniq the output since there could be entries such as
libavcodec55:amd64 6:10.2-1 installed: No available version in archive
libavcodec55:i386 6:10.2-1 installed: No available version in archive
To remove the packages one by one
% xargs -n1 -t -a ~/x/cruft.txt -i sudo apt-get remove --purge {}
You need to run these two commands (apt-show-versions and xargs) separately
since apt-get runs interactively and cannot get the input if run from xargs.
hope that helps
