@grauzone
You don't have to do that. If you follow the CI builds link, you will (after one more hop) land on https://ci.ubports.com/job/focal-hybris-rootfs-arm64/job/master/.
See the attached screenshot to find the link to then download an image.

@lupyuen According to the website https://devices.ubuntu-touch.io/device/pinephone/
regarding #pinephone :
The UBports Installer doesn't support this device yet. Click here to find installation instructions.
The device is still in early development, essential hardware may not work yet.
The link (Click here) will lead to a page telling "Build it yourself".
Let's run some #OpenSBI Experiments ... With Apache #NuttX RTOS on #Star64 JH7110 #RISCV SBC!
