Hello @Fla , Xenial was abandoned a long time ago, from what I see you didn't see that before being abandoned the file upload was working fine. A few months ago @Oren and others resurrected it but it's complicated and hands are missing. The latest thing they are doing is trying to make the image read-only and have OTA updates. A lot of things that worked on Xenial no longer work on Focal because it's like they started from scratch.

@flohack yes that's sad. On the other side Postmarket always said that their goal is to run vanilla Linux (https://wiki.postmarketos.org/wiki/Mainlining) so I'm not surprised they are putting their resources there and not on Halium.

Maybe a box with title “Daily Tip”, in the box something like: “(HOW-TO) Take a screenshot“, next line “(click to visit user guide)” Text would be a link pointing to the relevant item. A Daily Tip would reveal hidden features, but also be a great way to make people aware of a guide!
