I managed to start de A5E from nvme, but upgrading the packages fails.
Installing armbian-firmware_26.8.0-trunk.125_all.deb failed
With: data.tar lzma error....
Several months ago I got the same error but ignored it.
Now everything is almost working, I tried to find out what went wrong.
I can extract package with dpkg-deb -x on another system.
MD5sum is the same on A5E and other system.
This problem occurs on sdcard and nvme card.
Btw: it is the 4G version of the A5E.
Any idea how I can solve this?
