A few more hints. Debian's APT marks packages as either being installed manually or installed automatically as a dependency of something else. If you get a full list of packages that are installed then only the top level package names were installed manually. The rest were installed automatically. This is used to enable 'apt-get autoremove' functionality such that when libraries and other autotmatically installed dependencies are no longer needed that they can be detected as no longer being needed and removed. Better to separate out the top level packages and install those (which marks them as manual) and let them automatically installed their dependencies (which marks them as automatic) rather than install everything (which marks the libs as manual too). Meaning that those libraries will never be offered for "autoremove" later when they are no longer needed due to upgrades. You can use the 'apt-mark' command to list and change these. apt-mark showmanual apt-mark showauto apt-mark auto libfoopackagename You didn't say so I don't know why you wanted to know the package differences. I wanted to mention the above so that if possible you could still track packages installed manually versus packages installed automatically as a dependency. It will keep the "autoremove" functionality working for later as the system is upgraded and keep things cleaner. > Happy New Year ! Happy New Year! :-) Bob
