This has never been the case AFAICT. That's how apt-get autoremove works. Each package you specify on an individual apt-get install line gets marked as manually installed - the dependencies of those are not so marked. The marks can also be updated with apt-mark. When the top-level package is removed, apt shows the packages which were not manually installed in a list of packages which are potentially suitable for autoremove. > This may be a deficiency > which we want to do something about, but doesn't help right now. However, apt-mark status is probably not the answer to the original question which needs to be based on what packages are currently installed. -- Neil Williams ============= http://www.linux.codehelp.co.uk/
