I am running an incredibly old DietPi. It all works and I have it on a number of Pis. I set up a new one byfirst cloning the SD then customising it. By the time I got to “update” what I had was too old.
I need to get at an old repository so I can install “expect” … I seem to remember I managed this once in the past but of course what i did has fallen out the back of my brain
uname is 4.1.19+ #858 Tue Mar 15 15.52.03 GMT 2016 armv61 GN/Linux
power supply is not a problem
SD card is not a problem
The system works fine, but I am unable to apt install because the repository is out of date
Uff, looks like whezzy, for which no update path exists anymore on DietPi. In 4 steps the underlying Debian could be updated to => Jessie => Stretch => Buster => Bullseye, but it will require a lot of manual steps and fixes and produce an unclean system. I suggest to flash a new DietPi image and safe yourself the pain of this lengthy upgrade path .
