i installed ubuntu core 18.04 a few months ago with nextcloud on a raspberry pi4. i also connected 2 mobile devices and the first experiment was successful. i closed it for that time until i had time to add an external storage device. i opened the device yesterday to add the harddisk i bought. after a few minutes of running, the system loaded, and i connected to it with ssh, as expected.
so far so good!
i faced the issue of a new ip (i didnt set a static ip address), and i started searching for a solution to that (edit the config.php).
while im on that, suddenly the ssh notifies me that the system restarted. i waited.
and since then i was waiting. i tried several rebooting. i tried even giving it a full night.
the ubuntu loads and stays forever in the loading screen with the logo in the center of screen.
i cant even access the recovery mode with esc button or 1 key or long press on shift (https://ubuntu.com/tutorials/how-to-ubuntu-core-recovery-mode#3-using-recovery-hidden-boot-menu).
i have 2 questions:
- does anyone have an idea how to solve it?
- assuming there is no solution, and i need to do a reinstall, what have i done wrong? how should i do it better?
- could i save my data that was already on the nextcloud? for now it is not yet an issue, but im more worried if this kind of issue would happen when i really put ALL my data into it.
