It’s been a long move from the Eastern USA to the middle of the country, and my SD card was separated from my FreedomBox Pioneer for 2 months due to a logistical SNAFU. I recovered the card yesterday and plugged it in along with a keyboard and monitor, which I recovered two weeks ago from storage.
The Pioneer started up, and I got the boot screen, which went blank with a flashing cursor. Reboot and hitting keys did not stop the boot process. I made an image with
dd and restored the image to a clean high-endurance SD card, plugged it into the Pioneer and it started up fine.
The system is back on line. I need to upgrade the software. I believe I ran into some issues with the change on Debian from Buster to Bullseye and will have to modify the package repos. (I dealt with this last week on some servers at work I manage.) Hope to have my production FBX fully back on-line later this week.
Thanks for all the suggestions. I’ll keep the original SD card for later examination, including a deep examination of the log files.
