[Solved] Unable to complete manual installation of Ubuntu Touch

Alexey

Hi everyone!
I'm very new to Android devices and I'm trying to install Ubuntu Touch on used Nexus 5 which I bought recently. I do it manually because UBports Installer did not work for me (faced this bug). I'm doing everything from Ubuntu 19.10. Everything was fine until the final step:

adb reboot recovery

After that installation process does not start and the phone just reboots back into UBports Recovery mode with empty /cache/recovery directory.
Before the reboot I cat validate that in /cache/recovery directory everything is OK:

# adb shell "ls -l /cache/recovery"

Any tips whould be appreciated! Thank you!

@Alexey Don't think the install method will matter if there is not enough space on the device. Boot to recovery and use Android and Ubuntu actions to clear cache, wipe data etc. run the installer with wipe(snap version if you can) again. Guess if you just bought it you don't know if the partitions have been changed. There is a way to fix that but I don't have the link to hand. Ask or look through here https://t.me/WelcomePlus it's our install group. No harm in using both places. Good luck. Will check back later.

Alexey

Thank you for reply @Lakotaubp !
I already tried to clean up the partitions from Android actions and via CLI

fastboot erase cache
fastboot erase system
fastboot erase userdata

but it does not help. Both snap and manual installations stop at the same place.
This Nexus 5 I bought from software developer, he used this device for testing of his apps and he used some custom Android version so the partitioning is probably the case. If I understand correctly it is impossible to find out the real partitioning from the outside of Android device. I definitely need to find the way to restore it!
Unfortunately I don't have a Telegram account right now, because I don't use any of smart phones

Alexey

I managed to find the real partitioning of my device. I got compiled disk utils from here and pushed them with ADB to the Nexus. Partitioning looks like this now:

~ # ./gdisk -l /dev/block/mmcblk0
GPT fdisk (gdisk) version 1.0.3

Partition table scan:
  MBR: protective
  BSD: not present
  APM: not present

Could someone verify this output or share his own please? If 1.5 GiB system volume is Ok for Ubuntu Touch? Maybe something important is missing here? Also filesystem codes looks very strange to me... Sorry I'm completely noob at Android.

Hi,

I had a similar trouble as yours : unable to install UT => https://github.com/ubports/ubports-installer/issues/1070
In fact, I previously installed an unofficial rom of LineageOS => https://forum.xda-developers.com/google-nexus-5/orig-development/rom-lineageos-16-0-nexus-5-t3921162
To do it, I needed to resize the partition => https://forum.xda-developers.com/showpost.php?p=79928889&postcount=190
So, I have done a revert partitionning and everything went well, I was able to install UT.

Alexey

@lool_lauris hi! Thanks for replay! I've tried this method but got an error

~ # hh_repart -r
Chekcing size of partitions...
-- Unknown partitions --

I will try to ask previous phone owner how he did this disk layout.

lool_lauris

After flashing "twrp-3.3.1-HH-hammerhead.img", through the TWRP terminal did you first resize :

hh_repart -m

Reboot and then, still through the TWRP terminal :

hh_repart -r

Alexey

@lool_lauris thank for your support! I managed to solve the problem! Previous device owner gave me this link. So I did the following:

installed standard twrp version to recovery partition
uploaded hh_clamor_repartition.zip script to the phone via adb sideload.
run the script in recovery mode via "stock" command in terminal

After that I did successful Ubuntu Touch install via snap application.

Just for the case if someone will face the same problem I put the stock Nexus 5 32GB disk layout below:

Nice you succeed to install UT !
It seems that you did not follow this => https://forum.xda-developers.com/google-nexus-5/orig-development/repartition-nexus-5-repartition-t3844395 ... how did you proceed ?

Alexey

@lool_lauris I downloaded hh_clamor_repartition.zip and inspected its shell scripts. They are very simple if you are familiar with Linux system administration. Just usage of "dd", "parted" and "make_ext4fs" utils. Looking at current partitioning I figured out that my Nexus was affected by hh_repartition_32GB.sh script and to rollback the changes I just need to run the hh_stock_32GB.sh and that is it.
Also before that for safety I did backup of crypto and grow partitions to my laptop because those scripts do that too.
