I know this may sound a little weird, but today I flashed UT on my Mi A2 at the first try. Succesfully.
The only thing I did before was unlocking the device with fastboot oem unlock (and then follow the instructions on the device) and download the vendor image as the installer (0.8.8-beta, app-image) was suggesting. I had to give the path to vendor.img and that was it. I did not flash twpr, I did not downgrade to android 9, the installation went through without any issue and everything is working fine as far as I can see... Only the video capuring broke afte taking one single good video... hm . I'm on stable channel now.
thanks to everybody at ubports and the porters and everyone here in this great forum, hope this report is encouraging.

@unisuperbox Thank you to the entire team for all you do for this great project - thank you!

While watching you at the show, I could literally feel the burden you carry. I've felt that way before, but this time it was really clear to see and yes, to hear from you as well.
We normal users are greedy little animals, like children who always want more because it is so great what we are offered here, that's true.
But if we are reminded of that - and you rightly do from time to time - then we are also empathetic adults who know about the burden of your responsibility.
I want you to know that I am well aware of the weight of your responsibilities.
I probably feel as helpless as you do, because I can't do anything except a little communication and testing and some modest donations. But of course I know the situation, where everything becomes too much from my professional contexts as well. I think if you allow yourself that, the joy might come back. I hope it very much for you - and for all of us here. Good luck!

I bought a used Quintus with VollaOS 15 on it. The multiboot function didn't work. So I installed Ubuntu Touch 24.04-1.0 stable on it using the UBPorts installer. A very nice person on https://t.me/hello_volla explained to me that it wasn't necessary to downgrade. That seems important to me.
The installer even took care of unlocking the bootloader. The entire installation went smoothly. Great!
Almost everything works, even Dekko2, notifications, word completion, camera including video recording. I have 5G and I think even Volte (how can I check that exactly?).
Unlike what is stated here: https://devices.ubuntu-touch.io/device/algiz/, I can't get the headphones to work via the USB output, but that doesn't bother me. Fingerprint does not work too, but thats a known issue and doesn't bother me either.
One small bug: In the launcher, the Dekko2 icon doesn't stop counting; only restarting Lomiri resets the number.
Overall, I'm totally amazed!

There's also a Telegram channel for UT: https://t.m/utonvolla. Unfortunately, I don't know the Matrix chat (anyone?).
So this is my new daily driver and I will report issues from time to time. Thanks to all the Volla and UT devs for their amazing work on this port.

@stanwood lets buy one huge pizza to them all!!!!

@ubportsnews Would You be so kind and explain a little the affection of Daltons departure on the current projects and developments? I am not shure that I have understood enough of the structure of the different teams and so on... So it feels like an earthquake - is it one?

Wouldn´t it be a good idea to withdraw or lock the latest version of the ubports-installer due to all the issues reported all over the different sections of the forum? just a question... I´ve been reading such a lot of problems and answers advicing to take an older version. So I find it easier to withdraw the actual version so taht not so many people running in trouble with it.

There is an unofficial unlock-Tool:
https://xiaomitool.com/V2/
which worked for me on linux.

I also had to do the Ubuntuflashing using the UbportsInstaller twice... but now its kind of great!

@nauvpp Hi!
as keneda wrote in your other post it is not good to lock the device again. Have a look here:

and here:

@bhdouglass Onlyon Morph it looks like this...

@3t_ed I am such a happy UT user, too.

@ravachol Probably you can use the ubports installer.

@UBportsNews Thank You - please, what is the difference between this version and the version Marius published in the Openstore?

@UBportsNews merry christmas to you all and a happy new year!

@Charly same on Volla Quintus with 24.04.1.1 stable on it.

Updated.
Still no notifications on teleports and cinnyUt, but therefore the endless counter of dekko in the launcher is fixed.
Have some issues with the switch between 5g and LTE, sometimes I have to go into flightmode to be on the internet again by mobile data.
Today - so a few days after the update - uAdBlockNG stopped working, emptying cache and a reinstall didn't work.
Before and after the update I sometimes do not hear it ringing on the other side.
I have the impression that battery drain is less than before...
Headphones via usb are working now!

@Maik thanks!

hum, how to send you a private message?

@pparent Volla Quintus, 24.04.1.1 stable. I made a call and sound was very good on both sides. Thanks btw for your amazing work

I will try to upgrade to 24.04.1.1 tonight and report.

Device doesn't load update channels on wifi (neither on LTE nor on 5g), only on wlan.
