Hi @jetsonnvidia,
I meant… do you remember what was your previous version before you ran apt-get upgrade? You said this card has not gone through any upgrade for 1 years. But our OTA feature may not support some old release.
As for other users here, we have some result for this issue for far.
- This issue is due to lightdm greeter which is incompatible with new systemd
 - If you are using gdm3, then you won’t have this issue.
 - Every jetson platform has chances to hit this error if you are using lightdm. Not limited to nano-2gb.
