I am new to the odoo community, recently downloaded and installed the image of poxbox 16b in a raspberry pi 3, I would like to install hamachi

Note that the image comes without the APT package manager and I have not been able to install it since restarting the raspberry deletes the changes made

Try using the command to write but only save the files in home / pi

sudo mount -o remount, rw /

System that I have is the following

** raspberry pi 3b

** posbox_image_v16b

** Odoo 11
