I've been having issues lately with the later versions 22.11 and above. At some point when I reboot, I'll get those 3 "Read-only file system" messages on boot:

 

mkdir: cannot create directory ‘/root/.cache/oh-my-zsh’: Read-only file system
rm: cannot remove '/root/.zcompdump-orangepizero2-5.8': Read-only file system
zsh: locking failed for /root/.zsh_history: read-only file system: reading anyway

 

What is happening?!

Check (boot) logs why rootfs is mounted read-only.

This is related with your sd cards file system size. Please check your sd card partitioning. It is probably related with the size for armbian is too less, so there is no more room to write. or sd card might be read only.

 

To make it work, if you are on a linux environment :

sudo hdparm -r0 /dev/<your card file here> for disabling read only,

and you can use discs application on ubuntu to check the partitioning.
