Any known issues with installing from a live media?
(self.debian)
Debian is a free operating system (OS) for your computer. An operating system is the set of basic programs and utilities that make your computer run. Debian provides more than a pure OS: it comes with over 59000 packages, precompiled software bundled up in a nice format for easy installation on your machine.
The live installer sucks.
It is called Calamares, it is not well maintained upstream, and it doesn't support even trivial complexity like LVM or Encryption.
Use the regular install DVD or Netinst. You get to choose your desktop environment in the process.
