Hello
I have troubles with UT dual-boot upgrade. UT just reboots to recovery after upgrade was requested.
I have seen some relevant suggestions, but not sure how to fix the problem.
Can someone maybe suggest?

Here is the thread https://forums.ubports.com/topic/10432/ubuntu-touch-as-second-operating-system/7?_=1768510436778

said in Ubuntu Touch as second operating system:

sudo system-image-cli -v --switch 24.04-1.x/arm64/android9plus/rc

And if I try to do "Format data / factory reset" from the recovery after that, I got "ERROR: recovery: Read state file failed: No such file or directory"

Nothing changed in UT after that, I still have an old OS version, it resets only Volla OS

@Josele13
I have switched, but no luck, it always reboots to recovery mode, and I don't know what to do next. Do you?

@gpatel-fr
Thank you, that worked well!
You should just download the updated file and run
ubports-installer -vv -f vidofnir_esim.yml
in Linux

@opino
I support the topic, have same issue. I see that four month passed, but update from Volla side is still not available. Maybe you have found another way to update UT?

Hi
Are there any updates about that problem?
I have same issue

bolded textRe: Anyone tried installing another OS on a Ubuntu Touch X23

Hi

I have got following instructions on how to install Volla OS onto my Volla X23 phone which has installed by manufacturer Ubuntu Touch.

Here it is
https://drive.google.com/file/d/1ohEZOQpb0plpYZqh80TIVJIxdRwwol9T/view?usp=drivesdk

But even though I was trying hard with available to me combinations of UBPorts installer (latest 0.11.2 and 0.10.0) and environment (Linux, Windows), despite that flashing was always failing with the same error "Partition does not exist".

Here's screenshot
https://photos.app.goo.gl/defCQwhhmbGpjcsx9

If someone succeeded with that task, could you please share how. Or suggest me what I can try more?

I should mention that I have flashed Ubuntu Touch back again without any problems after failed attempt to install Volla OS.
