I can't get Libertine to work at all, and would appreciate advice from anyone who has. The chroot option seems to work to create the container, apps install correctly, I even get desktop icons, but they won't launch.
I'd guess that this issue (apps not launching) has to do with Wayland integration as in enabling apps in the container to write to the display. As other UBports phones use Mir, this is one of the many PinePhone exclusive problems.
I recently tried to research (= use of popular search engines) how to enable this (not for a Libertine chroot, but an Arch Linux ARM chroot) but gave up after 3 hours.
