You'll need to resize partition manually (gparted), then zerofree it (to 0 free space, reducing 7z size).
I use a desktop (LXDE), and created this bash script:
Once you've saved SD/EMMC to a .img:
- change
IMAGE_FPandIMAGE_NAMEaccordingly. -
Run it
#!/bin/bash { #check packages are installed if (( ! $(dpkg -l | grep -ci -m1 'gparted') )); then apt-get install gparted zerofree -y fi #------------------------------------------------------------------------------- #MUST LEAVE 50MB+ space or automation autologin may fail due to 0 free space!!! #------------------------------------------------------------------------------- #------------------------------------------------------------------------------- #ARMbian recreating partitions.

Yes, will do my best to get it run for devices I have here. (e.g. NanoPi Neo, OPi One, Odroid C1, Pine64) Crying around doesn't change anything. So let's launch us into image update.
Have playing around a little bit with
finalise. Nice script, so far so good. (Some little quirks, depending on tested devices, but let's move forward)Have some ideas, how to shrink ext4 partitions after running this. But better to ask, how you want or will do this, before I go about? Any tips or hints?
Thanking you in anticipation.
