Thanks a lot.
The installation went without a hitch.
The camera works much better than in 20.04.
voLTE is still fully functional on my Redmi Note 9 Pro in Belgium with Orange.
There's still the known problem that prevents Bluetooth pairing with the car.
As for the rest, I'm happy to adopt it, the OS is superb!

@libremax
Extremely interesting.
Necessary information that I was missing...
Thank you for sharing, and a thousand thanks to Alfred and those who make this possible.

@domubpkm
Glad to hear it!.
In the next release, i'll fix this size and will add global theme changes and relooking.

@Technotramp
Could you read this discussion, it's a good start place.

Hello.
Did you checked the usb parameters in System parameters?

@O.o.
Welcome!
I made this choice a year and a half ago and I have never regretted it.

Hello.
I'm trying the 24.04 (r85) on my Redmi Note 9 Pro.
I had an issue while configuring the device.
I have plugged a usb keyboard and after using the top tool bar to change the keyboard layout to azerty belgium.
The system parameter has crashed after i choose this keyboard.
After this, i can't launch system parameters nor any app on the phone (terminal, camera, ...).
The screen pop up and close just after.
Wondering how to look at the log files...

@PiotrBujakowski
Original Poster I guess.

@donieck
That's a possibility, which is why I suggested reinstalling the latest OTA for 20.04 to confirm or disprove this hypothesis.

@donieck
Another option would be to contact your operator to check how to connect your phone to their mobile network (or search for this setting among other users of this provider).
Usualy

in System settings / cellular / Provider and acces point name / Access point name / internet (sorry for the labels retranslated from french)
You'll have to restart to phone after any change.

@donieck
Hello.
Could you to downgrade to 20.04 stable with UBports installer ?
If the SIM card works with this release, try to return under 24.04 stable.
And if the problem is back, please tell us in https://gitlab.com/ubports/porting/community-ports/android11/xiaomi-redmi-9/xiaomi-lancelot/-/issues

Excellent username!

Hello.
Listening to Alfred yesterday during the Q&A (very interesting, as was his conference on UT, which is a must-see), I wondered why it wouldn't be possible to free up space by modifying the UT installation process.
First, install the OS without any applications, and then, on first boot, download the applications that are currently included in the OS and install them in the user space.
This would save space and solve the strange behaviour encountered when attempting to uninstall these applications.

@UBportsNews
The use of snap packages under UT takes place in a specific context (AppArmor, read-only file system, custom OS implementation, etc.).
Are there any links where information is available to understand how snap works in this context?
Thank you to everyone who gives their time and skills to advance this essential OS.

Not so hard and usefull
you must know which yaml file is used for the wifi in /etc/netplan
as root cd /etc/netplan and cat yaml files.
nano 90-NM-5f1fe55a-2996-4485-b6b3-a75fe76edc62.yaml (ie)
Then in the wifi one
replace

      dhcp4: true 
with
      dhcp4: false
      addresses:
        - [your wanted IP]/24 (or less)
      routes:
        - to: default
          via: [your router IP]
      nameservers:
        addresses: [your DNS1, your DNS2]

save it
and validate it by
netplan apply

@gpatel-fr
You could fix IP (as I did)

@gpatel-fr
It looks like things has changed since the tests we made in march...
Sorry I haven't verified that it was still working
I had some trace in terminal launching (as the service)

sudo systemctl stop ofono.service
sudo /usr/sbin/ofonod -d -P ril --nodetach

To run it as a service
add "-d" to the ExecStart command in /usr/lib/systemd/system/ofono.service.d/lxc-android-config.conf
