Update to 20.04 failed, HASH ERROR

Hi,

I tried to upgrade my Xiaomi Remi Note 9 Pro to 20.04. Downloading part went fine but then I got following error:

Updates failed

FileNotFoundError: http://system-image.ubports.com/pool/ubports-415279e61546762c23b21cd658a0ad0054ca52cf738684128dff675a5b991061.tar.xz:HASH ERROR

I checked if file that URL points to exists and it does, I was able do download it.
Is there something I could do to troubleshoot the issue? If not is there an alternative way to install UBports 20.04 on my phone that already has 16.04 installed?

Best Regards,
astromehazu

Thanks for your help. Setting phone in fastboot mode was the missing link, after enabling it instalation went fine. I had to enable repartitioning of internal storage otherwise I ended up in boot loop.

Hi @astromehazu

The dumb thing to do is try again, maybe with another cable.
The file might have been somehow corrupted.

If you run the installer from a console you should be able to see the log traces (but maybe that's where your found the error).

But the dumb method works more often than not.
Also trying with a different cable might help if you have a faulty cable.

And a last piece of advice would be to back everything up and use the wipe option.
It's better to start clean then to keep old config files that can mess with your new install.

I did OTA update there were no cables involved.

How do I run updater (installer) from console? Is it computer or phone console?

One option is to clean install new version but ubports-installer did not recognize my phone (my guess is because it does not have Andoid on it but UBports). Is there a way to reinstall UBports on a device that's already installed with UBports?

@astromehazu
Sorry my message wasn't clear.
Yes I thought you did the install with the ubports-installer.

You can try again OTA, but it is easy enough to use the ubports installer.
You just have to manually select your device.

Mine is a Pixel 3a and wasn't recognize as well. But the install process worked pretty well when I was told how to boot in fastboot mode

You can also refer to this documentation if you have some problems:
https://docs.ubports.com/en/latest/userguide/install.html#

I wish you good luck.
