Nextbox No space left error on firmware upgrade

ℹ️ Support 📦 Appliances (Docker, Snappy, VM, NCP, AIO)

I am running a Nextbox-snap with an Ubuntu image on a Rasperry 2.
My probem is after running upgrades I always get an error message stating that initramfs-tools can’t complete the post-installation process, stating that the /boot/firmware-folder is out of space. This process creates backup copies of the old files in the firmware folder, resulting in missing space and incomplete initrd.img an vmlinuz files, which makes the system unbootable.

In my configuration the folder
/boot/firmware is the first partition of the sd-card, which contains the firmware. Initially it contained only 60 MB rougly, so I enlarged it to 400 MB. But the error message keeps on popping up. So I am wondering what is going here and would appreciate any help.

My System:
Linux nextcloud 4.4.0-1017-raspi2 #23-Ubuntu SMP Thu Jun 30 21:50:40 UTC 2016 armv7l armv7l armv7l GNU/Linux

Can I see the output of df -i, please?

Hello kyrofa,
thanks for helping me.
Here is the output:

This is not the state of the /dev/mmcblk0p1 after the failed upgrade. As the system did not reboot properly after upgrade I reflashed the firmware partition with a backup I had made before.

Interesting, can I also see the output of mount, please?

Ah, fat? Why did you go that route? That explains the inode output. We’re a bit out of my wheelhouse here then, but check this out:

Not sure. I did flash the sd-card long time ago with Snappy Ubuntu. Me myself I did not choose that filesystem. You suggest, I should use another one like ext? I’ll give it a shot.
