I cloned my Ubuntu 18.04 installation to an SSD with the program "systemback" and named it Ubuntuclone. I use Ubuntuclone with my MacBook Pro for a separate OS.
While my mac is booting I hit the alt button. I then see three options:
- MacOs
- Windows
- EFI
When I choose Windows or EFI, Ubuntu works fine but the problem is this, when I restart or shut down the Ubuntuclone and open it again all the things I have done is gone. For example I have to reenter the password of the wifi, or a saved document is gone. Everything goes back to cloned status and I cannot save anything.
I open any suggestion to solve this.
Thanks in advance.

The output of the mount command reveals the overlay being used in the root filesystem:
Where /cow/upper directory contains your changes made to the system. The filesystem.squashfs is a read-only filesystem, so the base is not overwritable. /cow/work is the working directory for temporary data.
Make sure the /cow directory is writeable in the new drive or create the /cow/upper and /cow/work directories in your SSD with live USB Ubuntu system.
