Google Cloud Print on Ubuntu 16.04

As I wanted to be able to easily print from my phone and chromebook, Google Cloud Print was the solution.

Here are the simple steps that I used:

1. sudo apt install google-cloud-print-connector
2. gcp-cups-connector-util init
• It will require you to enter a code at https://www.google.com/device to create the OAuth credentials
• save the created config file somewhere safe
3. gcp-cups-connector -config-filename gcp-cups-connector.config.json

Don't forget to install Cloud Print by Google LLC on your smart phone!

Installing Unifi Controller on Ubuntu 16.04

Here are the steps that I had to do to get Ubiquiti Unifi Controller software installed on Ubuntu 16.04

1. Add the gpg key:
• sudo apt-key adv --keyserver keyserver.ubuntu.com --recv 06E85760C0A52C50
2. Add the repo:
• echo 'deb http://www.ui.com/downloads/unifi/debian stable ubiquiti' | sudo tee /etc/apt/sources.list.d/100-ubnt-unifi.list
3. Update Sources:
• sudo apt update
4. Install the software:
• sudo apt install unifi

Unfortunately, this resulted in JAVA_HOME not found errors in /usr/lib/unifi/logs/server.log. This is because the unifi software requires Java, but it couldn't find it. I tried to point to the Java 9 path, but that just resulted in errors like: /usr/lib/unifi/data/keystore (Permission denied). Apparently, the software only works with Java 8. To resolve this issue, I installed Java 8 and restared unifi with the following commands:

• sudo apt-get install openjdk-8-jre
• sudo service unifi restart

Then head over to https://localhost:8443 to complete the setup
