comment What does this “printf” command do?
This seems to be shell dependent. Is your printf a builtin? /usr/bin/printf on Ubuntu 14.04 gives an error: printf: %(: invalid conversion specification. If you're using bash. Try man bash for builtin documentation.

comment Pipelight unmet dependencies
Glad you solved it yourself. That's the best way to learn. I suspect what happened here may have been the order of commands. For a totally new repo, (like ppa:pipelight/stable above), the repository needs to be added first, then an apt-get update is needed to update the index of packages, latest versions available, etc. Finally apt-get install <package_name> needs to be issued for the actual install. Adding new repositories is a relatively rare operation (and needs to be done only once per repo).

comment Troubleshoot networking issues
You need to isolate the cause first. The biggest stand-out is that /etc/network/interfaces on the laptop is supposed to give a static address of 192.168.1.100 to the eth0 interface, but that doesn't show in the ifconfig output (unlike the wlan0 wireless interface there's no inet: address in the eth0 section). Suggest to try bringing the eth0 interface up with: sudo ifup eth0 . Also RX/TX packets of 0 means nothing was ever attempted to be transmitted on eth0.

comment Version 14.04 crashes too often
What do you mean by "version 14.04 crashes"? What are "couple of other programs"? What commands do you invoke? What error messages do you see?

comment Pipelight unmet dependencies
In order to increase the chances of a helpful answer, please provide the 2 most important missing parts in the question: 1) What exact command was typed at first, and 2) What error message was seen (e.g. what unmet dependencies did you get?) expressions like "failed miserably" and "no luck" are not helpful and not a substitute for the actual facts. Similarly for "add the repository" (which one?) etc.

/etc/ssh/sshd_config shouldn't be empty. Do you have openssh-server installed?

If this is your computer, your own username/password should be able to gain root privileges and fix things. On Ubuntu, by default, the owner of the computer (with his/her credentials) is allowed to sudo. HTH.
