Lack of fdisk for image based on Ubuntu 22.04 (develop-lsdk-21.08)

[hitpony]

Hello Sir

Not sure this is an issue, could you please help to check?

I have used the guidence here to build an image from docker:

• Follow the step from README.md for build the image:
  https://github.com/SolidRun/lx2160a_build/tree/develop-lsdk-21.08

• Command used to have jammy (Ubuntu 22.04) instead of Ubuntu 20.04 (default), image can be built successfully:
  sudo docker run --rm -i -t -v "$PWD":/work -e UBUNTU_VERSION=jammy lx2160a_build -u $(id -u) -g $(id -g)

• Burn the image into SD card and follow the steps from to copy to eMMC:
  https://solidrun.atlassian.net/wiki/spaces/developer/pages/197494288/HoneyComb+LX2+ClearFog+CX+LX2+Quick+Start+Guide

• Following three commands are used, and run successfully:
  load mmc 0:1 0xa4000000 ubuntu-core.img
  mmc dev 1
  mmc write 0xa4000000 0 0xd2000

• After boot from eMMC (via jumpers), and log into Ubuntu 22.04, there is no fdisk command found, so the eMMC can not be extended to full size.

• Search from Ubuntu community, said that “fdisk” is not included from Ubuntu 22.04 by default (tbc), need to run apt install fdisk to install.

• try to run "apt update" and "apt install fdisk" to install fdisk, but report there is no enough space for apt update.

• run df to have the following:

  root@localhost:~# df
  Filesystem 1K-blocks Used Available Use% Mounted on
  /dev/root 338867 274364 42487 87% /
  tmpfs 7109588 0 7109588 0% /dev/shm
  tmpfs 2843836 732 2843104 1% /run
  tmpfs 5120 0 5120 0% /run/lock
  tmpfs 1421916 0 1421916 0% /run/user/0

• The size of the rootfs should be 350M, I tried to use the following comand to re-build the image to have larger rootfs (640M):
  sudo docker run --rm -i -t -v "$PWD":/work -e UBUNTU_VERSION=jammy -e UBUNTU_ROOTFS_SIZE=640M -e DEBIAN_ROOTFS_SIZE=640M lx2160a_build -u $(id -u) -g $(id -g)

• After burn the new image to eMMC, I still got the same size of rootfs (350M?), so still can not install fdisk via apt install fdisk. seems the parameter of -e UBUNTU_ROOTFS_SIZE=640M is not working.

Could you please help to check how to have fdisk command for Ubuntu 22.04 image?

Thanks in advance!
