About UBsync
UBsync is the featured application for OwnCloud/NextCloud synchronization on Ubuntu Touch.
Common UBsync Recommendations:
- Do not synchroniz••••••••••••••••••••••••••••••e the entire home folder, because it can be quite big and certain fast-evolving files (caches, or profiles) may induce many file versions in the cloud. Rather set up several targets and select individual folders.
- UBsync can be used to back up your app configs to Owncloud/Nextcloud
Application sync support tips:
- UBsync can be used to sync Activity Tracker and Nextcloud GPXedit apps
- UBsync can be used to sync Crazy Mark app with Nextcloud Notes
- UBsync can be used to sync your music files
- ...
App Permissions:
UBsync requests explicitly following permissions:
1. Online Accounts - to be able to use Owncloud/Nextcloud accounts already set up in system settings
2. Networking - as a cloud synchronization app, it naturally needs network access
Additionally, UBsync is an unconfined app, which means, that it is not limited by any AppArmor security policies.
This application needs to be unconfined, as the pre-defined AppArmor policies do not permit all of UBsyncs' vital features:
1. gain read/write access to any folder you wish to synchronize
2. create the backend daemon (Owncloudsyncd) for background synchronization
3. UBsync-ui to Owncloudsyncd communication through DBUS
As unconfined apps may introduce security risks, you can review the app's source code or even build the app by yourself to be sure, that the app is not harmful.
Please note, that unconfined applications in OpenStore are manually reviewed.

Unfortunately, ubports do not support identification with "2FA", it is impossible for me to identify myself.

Unable to sync with my instance which I've been able to do on other systems. Calendar sync works though so there is some working connection. Where to find error logs?
