Listen to the podcasts mentioned in this discussion.
Yes, I have ny servers upodated to 31 and did the offered 1.55.4. update before, it is offered to running instances only (ssh boot prompt).
I have no clue of your Odroid hardware, but nextcloudpi there
sudo ncp-config
-> system -> info
will start with an overview
pi@nc-rspios5:~ $ sudo ncp-config
Running nc-info
Gathering information...
NextcloudPi version v1.55.4
NextcloudPi image NextcloudPi_06-01-25
OS Debian GNU/Linux 12. 6.12.47+rpt-rpi-2712 (aarch64)
ncp version 1.55.4 is only offered to running instances and no image is provided on github to start with.
But this version offers support of nextcloud 31 which gives you some more month support, ncp maintainer is ttrying
to get supprt done to nc 32.
You may try
sudo ncp-update
and then
sudo ncp-update-nc
You may examine this, diskpart, gfdisk, cfdisk, et.al., even is the cable connection clean?
You may consider to check with raspianOS, as it is the best OS supporting rpi5.
