Disk, power, and internet check
The next screen checks and confirms the installation environment.
Note that it says at the top "For best results..." — these are not strict requirements, they are suggestions. If there isn't sufficient disk space available, you will have the opportunity to free some more, or assign some existing partition(s) to this installation; if you are are brave enough to start the installation without power connected, that's up to you — if you don't have an internet connection, there are a couple of optional things you won't be able to select during the installation, but otherwise, the basic installation will work just fine.
If you have an internet connection, you can choose to have ubiquity download and install the latest updates during installation, and you can also have it install some commonly used third-party software packages along with the installation.
