If I try to upgrade on Lucy using any sysupgrade.bin, everything seems ok but after rebooting the same version remains.
On bash/SSH I see always the following error with sysupgrade -v/ -F/- n/etc:
Image metadata not found
umount: can't unmount /dev/pts: Resource busy
umount: can't unmount /dev: Resource busy
So I am stuck on 1.4.8 version.
Desperated and taking into account I am quite newbie I also tried several solutions like this:
Unfortunately, nothing happened.
Thanks for your job and Merry Christmas!
After 2 weeks complaining myself this afternoon it seems to have been solved.
I had to use an internet connection and not scp.
I downloaded using wget into /tmp
Afterwards, I tried with mtd -r write (sysupgrade shows error)
Everything seems OK
