Installing Ubuntu touch is pretty easy. The default login is phablet as is the password. It should just login itself but you will need that when using the terminal for things requiring sudo or when changing some settings in the GUI. If you can use an ethernet cable at the setup stage it avoids any wifi issues (that are being worked on). Selection by mouse is a bit buggy still, sometimes selecting with "Tab" then hitting "Return" will be easier.
Download an image from
https://ci.ubports.com/job/rootfs/job/rootfs-rpi/90/ This is currently the most stable (15th December). Feel free to experiment with newer images and let us know your experiences but there may not be someone else to compare notes with yet.
Flash SD card:
Use DD in the Linux terminal or on windows
https://www.balena.io/etcher/ to write the image to the sd card once you have unzipped it. Raspberry Pi sites will give details of how to do all this.
Remember to expand the main partition to fill the card. Easiest to use a card no bigger than 32GB.
Swap:
It works better with swap. Type sudo apt-get install dc dphys-swapfile in the terminal if you want a swap partition of 2GB
Development:
https://gitlab.com/ubports/core/rootfs-builder-debos and the multiple deb packages that are used are built on
ci.ubports.com with the source on
github.com/ubports/The build "scripts" can be found here:
https://gitlab.com/ubports/core/rootfs-builder-debos/blob/master/raspberrypi.yaml please send pr's here to improve the images.
Apps:
https://forums.ubports.com/topic/3323/arm64-apps-and-testing is a good place to start when looking for arm64 apps and how to install and test them.
Some of the arm64 apps being tested for the pinephone and other arm64 devices work, others just shut down or behave oddly. Openstore is getting more arm64 architecture apps.
Sound is not sorted yet and neither is the Pi camera. However the Pi touchscreen works. Expect bugs and crashes - we are at an early stage. Probably more Alpha than Beta testing but things are developing quickly. Wifi pretends to work but ethernet works well. Have fun and please use the UBports forums, Github or associated Telegram groups to learn more, to give feedback or to help solve bugs or other issues.
