I am also using aptitude purge ~c
which removes orphaned configurations by already deinstalled packages, and aptitude purge `deborphan --guess-all` which deinstalls all orphaned libs and packages. Here yo uhave to look, if something unwanted is deinstalled, but in my experiences this very rare happened. In that case, i.e, when a library is missing, I am just reinstall this partiular one. For uninstalling old kernels, I also like to use aptitude purge ~n4.8.0-1-amd64-* (the same is apt-get --purge remove 4.8.0-1-amd64-* which installs all packages with 4.8.0-1-amd64 in its name. And as the version no other package is using, it deinstalls just that kernel, headers and built modules. Note: Take a look, before confirm! Happy hacking! Hans
