eepDater provides a very simple, but functional, GUI for selecting which package updates you'd like to install on your computer via apt-get:
You can simply check the box for the updates you'd like to install and then hit the apply button. Hitting refresh will check for package updates:
One thing worth noting is that eepDater does not include any code for escalation of privileges for installing software. This means you should launch it with something such as eSudo.
If you are using at least Bodhi 3.0.0 you can install eepDater on your system with the command:
sudo apt-get install eepdater
For anyone else out there, you can find the eepDater source code on GitHub here.
