Describe the bug
It's currently impossible to build a pwnagotchi image due to a number of reasons:

• The image's main apt repo changed from "stable" to "oldstable" which causes the initial apt-get update to fail.
• The re4son kernel apt repository keys are expired.
• The arm-image packer plugin repo has been renamed.

To Reproduce
Steps to reproduce the behavior:

1. Run make image

Additional context
I recently started working on building a pwnagotchi but got a Waveshare v3 display. I saw that support for the display had been merged but that no pwnagotchi images have been released in over a year. I tried to build the image myself but kept running into issues.

I'm currently working on a fix for most of these. 👍
