+**WARNING:**  It is recommended to avoid using this command.
+  * The command **apt-get upgrade** is very obedient.
+    * It never tries to remove any packages or tries to install a new package on its own.
+  * The command **apt-get dist-upgrade**, on the other hand, is proactive.
+    * It looks for dependencies with the newer version of the package being installed and it tries to install new packages or __remove__ existing ones on its own.
+    * It has a “smart” conflict resolution system. It will attempt to upgrade the most important packages, at the expense of the less important ones.
+      * This may lead to the removal of some packages, which you might not want. This is the main reason why dist-upgrade should be avoided on production machines.
