Hello everyone, the broken upgrade process is my fault and I apologize everyone for the inconvenience.
The reason behind the broken upgrade process is the merge of the rockchip and rk322x families, which introduced this regression.
The problem went undetected because upgrades happens once in a while when there are armbian new releases.
I will address the issue as soon as possible, in the meantime please avoid upgrading to latest armbian version. I will post here when I will be sure the issue is fixed!
