If you want to stay on the bleeding edge, install the `ethereum-unstable` package instead.
After installing, run `geth account new` to create an account on your node.
You should now be able to run `geth` and connect to the network.
Make sure to check the different options and commands with `geth --help`
You can alternatively install only the `geth` CLI with `apt-get install geth` if you don't want to install the other utilities (`bootnode`, `evm`, `disasm`, `rlpdump`, `ethtest`).
