Nextbox Software completely dead

Hello!

My Nextbox stopped working out of nothing on Wednesday Night (no config change of something was done). Since then i am trying to find the reason for this. I activated ssh when i installed it so i can try to debug a little. Corrently docker wont start the containers with this error:

root@nextbox:/usr/lib/nextbox-compose# /usr/bin/nextbox-start-compose.sh

I already did a soft and factory reset but that doesnt change anything. Help is highly appreciated.

Thanks in advance.

Same problem here. Is there any solution yet?

What’s your version of the nextbox app?
I once had an issue with an eternal boot loop, and that was because my app was very old.
To update, what i did then was the following :

sudo systemctl stop nextbox-compose
sudo systemctl stop nextbox-daemon
sudo dpkg --configure -a
sudo apt-get update
sudo apt-get install -yq --fix-missing --fix-broken --autoremove nextbox
sudo apt-get -yq autoclean
And then reboot (“sudo reboot”)

Please note that I am just another user, and his advice is definitely not from Nextbox.
