Ubuntu Touch is the privacy and freedom-respecting mobile operating system by UBports. Today we are happy to announce the release of Ubuntu Touch 20.04 OTA-10, a maintenance release of 20.04 series. Ubuntu Touch 20.04 OTA-10 will become available for the following supported Ubuntu Touch devices over the next days:
* Google Pixel 3a and 3a XL
* JingPad A1
* Lenovo Tab M10 HD 2nd Gen WiFi / LTE
* Rabbit R1 (new in this release)
* Xiaomi Redmi Note 9 Pro/Pro Max/9S
What's new?
Ubuntu Touch 20.04 OTA-10 contains only a minimal number of changes due to our current focus on Ubuntu base OS upgrade. The most important change in this release is the inclusion of the new Ubuntu Touch upgrader, which allow users to upgrade to Ubuntu Touch 24.04-1.0 once it's released.
The full list of changes (from UBports) is included at the end of this post.
How to get Ubuntu Touch 20.04 OTA-10
Existing Ubuntu Touch users
Existing users of Ubuntu Touch on Stable channel (which is selected by default in the UBports Installer) will receive the OTA-10 upgrade by using the Updates screen of System Settings. Devices will randomly be allocated the update from today through. This spread is to give us a breathing space to stop the roll out of any bad update (should that ever become necessary), and is **not** to accommodate any bandwidth restrictions.
There is also the system update broadcast facility, which will send each online device a trigger message. If the device can find its update, it will be downloaded for you and when everything is ready, a notification will pop up and you can install right away. This only works if you have set up that updates can be downloaded automatically.
If however you would like to receive the update immediately, turn on ADB access and issue the following command over `adb shell`:
sudo system-image-cli -v -p 0 --progress dots
Your device should then download the update and install it. This process may take a while, depending on your download speed.

Side note: an update on Ubuntu Touch 24.04-1.0
Ubuntu Touch 24.04-1.0 was scheduled to be released together with Ubuntu Touch 20.04 OTA-10 today. However, we've discovered an issue where some devices fail to boot after installing Ubuntu Touch 24.04-1.0 RC 2, which requires us to delay the release of Ubuntu Touch 24.04-1.0. We're looking into it and will provide update as soon as possible.
