Ubuntu Touch OTA-24: Last feature update before moving to Ubuntu 20.04


With OTA-24, the developers at UBports have released the last feature update for the mobile operating system Ubuntu Touch based on the now extremely outdated Ubuntu 16.04 LTS (“Xenial Xerus”). The switch to Ubuntu 20.04 LTS (“Focal Fossa”) is then planned for 2023. Before that, a bugfix release should appear.

Ubuntu Touch OTA-24 – Release Notes

For the upcoming OTA-25, the developers are providing error corrections as well as LTS support in prospect before the long-awaited change to Ubuntu 20.04 LTS is supposed to be in the house.

This is the last OTA for Ubuntu 16.04 (xenial) with major features. The next OTA-25 will be mainly security fixes and long-term support updates for xenial.

Ubuntu 20.04 (focal) base has progressed quite far and so we are preparing everything for the switch. This also means that we will prepare OTA support for 20.04!


The rollout of the latest version on compatible devices has already begun and can now be triggered manually via sudo system-image-cli -v -p 0 –progress dots.

Support for Pixel and Fairphone

Meanwhile, 87 smartphones and tablets are supported by Ubuntu Touch, including the Pixel 2 and Pixel 2 XL, the Pixel 3a and Pixel 3a XL as well as the Fairphone 1, 2, 3 and 4. Numerous smartphones from Xiaomi, OnePlus and Sony are also represented.
