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!

@messayisto I am totally ashamed to admit, that it was only a wrong password. I had to look inside my router to get that. So sorry ...
To repent, I will immediately donate something

Congratulations anyway to this great port, the OPO 5 is now my daily driver. And again thanks for your work.

@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?

@Peter-Gamma there is support for many languages including german. so no problem to write words like grüezi, schächteli or löli

This is kind of a pull request, or a suggestion, no: a deep wish of mine!
In the legendary times of the N9 there was a game called "Heebo" by developper Mats Sjöberg. It was later ported by some people to Sailfish Os, because its totally open source. I love this game, you can download it here:
https://openrepos.net/content/hooddy/heebo
I wrote a mail to Mr. Sjöberg, and he answered that it shouldn't be too hard to port his game to Ubuntutouch. Unfortunately he doesn't own an Ubuntu Touch device, and without that it seems to be impossible to do any conversion.
He further writes: "The software and graphics are all open source, so if you know of someone who does know how to develop for Ubuntu Touch, I would naturally have no objections to anyone else porting it, and I would be glad to help in any way I can. In fact, the Sailfish and Android ports have been done by other people. I only created the original N9 (MeeGo) and Symbian versions."
So my question is: Is somebody here, who could port it? Unfortunately I'm not a developper at all, so I cannot do it, but if I could help, I would!
Thank You for listening.

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.

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

and here:

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

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!

@MrT10001 No, unfortunately not. Neither a restart nor switching the device off and on again helps.
Perhaps @rubencarneiro can say a word about this?

@MrT10001 I suceeded in installing the global version on my oneplus nord n10 which was labelled as BE2029. Then installed UT -first I tried noble, which gave me an error message, then focal - everything is working fine.
I have only one question for now: I switched to RC-channel, got an update, still everything is fine. Only when I look for updates now I get an ever spinning wheel. Someone experienced this too?
Nonetheless a big thankyou to @rubencarneiro for the great work on this port.

@uwahl same on opo5, rc, focal

@Lakotaubp @MrT10001 posted on telegram in the Q&A group, that he had general problems with the installer... Maybe a warning should be issued?
Unfortunately, I have not yet been able to test this myself because I do not have a device available.

@danfro https://dpaste.com/ATTBQZVFR
hope that helps

@danfro Installed from artifacts, cleared the cache again, app still crashes.

@danfro hum. The only thing I can say that I created a new file before. Then I tried to copy one word from this file and pressed it. Tedit crashed. I openend it again while another app was running (Morph). I tried to switch from tedit to the other app and it crashed again.

@stanwood good point, I'm not shure, too...

@domubpkm same on opo5, focal, rc. also swiping leads to a crash as well as switching between applications.

@UBportsNews Can somone be so kind to explain the pulse-audio issue that led to the early ota 7? Thanks!
