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.imgorubuntu.imgetc.But I can't find any
imgfile related to theroot partition.Here is

Thank you for your time.

Why do you feel you need to extend your root partition?
-
@arubislander probably to run apt I would guess - basically don't run apt, there is no need to extend your root partition.
-
Your device most likely have real partitions. It's only easy and simple to extend the root if it is just a loopback. Also it's not advisable unless you know what you're doing. An OTA update may remove all your changes and installations in the root or worse break your system.
-
@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.
-
@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
-
@sddwt Your use case isn't ideal with UT anyway. You'll probably have better results with Droidian.
-
@kugiigi Thanks, I will check that project, seems it's more suitable for me.
