I try to install chromium and get this:

This only happens in Armbian 23, in Armbian 22 both Ubuntu/Debian images everything worked well.

Any way to solve without rebuilding image?

squashfs module is present in kernel config for rockchip. Make sure it is loaded (lsmod)

Providing logs with 

armbianmonitor -u

 helps with troubleshooting and significantly raises chances that issue gets addressed.

@Werner

Yes, squashfs is listed in lsmod, but it does not seem to be mounted.

 

Tried using ppa version instead of snap?

I reinstalled snapd, rebooted and the problem vanished. Don't understand why it appeared though.
