+1 to this. I have two units. One updated fine using SSH. I updated the other via the web gui. It looked OK until I tried a reboot – it now bootloops (plugged in via HDMI to inspect).
If this helps, error messages / symptoms:
- On boot, it fails to mount the eMMC card on /mnt/vfat. Then tries e2fsck, and tries to umount (fails with “nothing to do”)
- Starting DietPi-Services, it complains: can’t lock /var/run/cron.pid, other PID may be 1968.
- Just before login screen, flags: DietPi-Process-tool | An issue has occurred.
- Then briefly presents the login screen, before immediately stopping services and rebooting.
Can post pics of above if helpful (am snapping with camera as they flash by).
Would reflash eMMC module, but who knows where adapter is. Will try a via micro SD, per @John_Aiello (whose pain I now share).
Thanks.
