    • RE: Don't know how to extend root partition.

      @kugiigi Thanks, I will check that project, seems it's more suitable for me.

    • RE: Don't know how to extend root partition.

      @kugiigi Thanks for the reply, I already gave up on that, it's too risky to do that. And I don't think it's a good idea to resize a filesystem unlike the loop 😞

    • RE: Don't know how to extend root partition.

      @mateo_salta correct, I am trying to use it as a micro server like raspberry pi, so APT installations are required. I have mapped soft link to some directory like apt cache to avoid run out of space, and trying not to install more.

    • Don't know how to extend root partition.

      It's so great we have a place to seeking the help. My partition is super wired that I don't know where to start.

      My phone is Xiaomi6 (AKA mi A2), the Ubuntu touch is version 16, latest dev version.

      And I have seen many people extend their partition by extending the system.img or ubuntu.img etc.

      But I can't find any img file related to the root partition.

      Here is df -h:

      The /userdata dir doesn't contain any img file, though loseup have such outputs:

      root@ubuntu-phablet:/userdata# losetup
NAME       SIZELIMIT OFFSET AUTOCLEAR RO BACK-FILE
/dev/loop0         0      0         0  1 /var/lib/lxc/android/android-rootfs.img

      Now my rootfs will run out, I am very concerned about that, if someone could show me a way to solve this problem, I will be very appreciate that.

      Thank you for your time.
