With every release upgrade comes many changes across the entire landscape of packages. Naturally, an extremely large change like this can cause problems, so **we strongly recommend you back up your files**. Also, if your computer is one that runs on a battery (such as a laptop), please ensure that the power is connected, as it may take a while and unexpected power failures could be disastrous. Also keep in mind upgrading from a previous release will download will take time and data.

This way of upgrading involves the command line and is also useful for server upgrades. Unfortunately with main Ubuntu and Lubuntu dropping 32-bit upgrades, 32-bit upgrades after Lubuntu 18.04 are not supported.
