OS update channel : 20.04/arm64/android9plus/stable
OS build number : 2023-W13
Kernel : 4.4.153-lineage+ (arm64)
Build ABI : arm64-little_endian-lp64
Device Image part : 20230321-5475
Device build description : lineage_cheeseburger-userdebug 9 PQ3A.190801.002 270 test-keys

Update downloaded on 07/30/23.
After clicking on "Install", the phone reboots and the recovery screen appears. Nothing more happens, I can navigate through the various options... On reboot, the system launches normally, but the update doesn't install. I try again and get the same result.

Same here on Volla.

And by reflashing the device ( without wipe ) ?

That didn't work either. Using ubports-installer_0.10.0_linux_x86_64.AppImage
Phone reboots but in charging mode, Ubports installer stuck on "Flashing firmware..."
After waiting, I turn on the phone with the button, it starts normally, no update.

Thanks for the link. After reading that some people had managed to do the update, I tried again.
ubports-installer still freezes on the recovery screen. Restarting in fastboot mode, the process resumes... then freezes again. I've managed to complete the installation by restarting several times, sometimes returning to fastboot, sometimes to recovery... I can't give exact instructions but it eventually works.
