According to the documentation for deborphan, "deborphan finds packages that have no packages depending on them ...". That's not what I want. What I want is a list of installed packages that are not listed in any repository found in /etc/apt/sources.list. This is what aptitude refers to as "Obsolete or Locally Created Packages". As an example, lilo has no packages depending on it; but it is included in Debian stretch, which is listed in /etc/apt/sources.list. Therefore, by aptitude's definition of obsolete, lilo is not obsolete. On the other hand, libapt-pkg4.12, which still exists in jessie, was recently removed from stretch. Therefore, for stretch systems, libapt-pkg4.12, though it may be installed by reason of a migration from jessie, is classified as obsolete. It is installed, but it is no longer installable from the Debian archive. -- .''`. Stephen Powell <zlinux...@wowway.com> : :' : `. `'` `-
