networking - Is it possible to update Ubuntu Live USB stick?



I built an ubuntu 16.04 live usb stick from ubuntu iso file using refus month ago, and it has been working great. There was only one issue though: my router doesn't have DHCP enabled (it's complicated why ) so when booting into live Ubuntu, there is no network connection.



Is it possible to update the live Ubuntu? I mean it won't be possible if it were a CD, but given it's a usb, is it possible to update /etc/network/interfaces and manually assign ip/gateway stuff? or have some packages pre-installed (the default Ubuntu 16.04 iso is missing a few great tools)




I tried but it seems after re-boot, those changes are lost. So it seems that the Live Ubuntu is write protected.
Can someone shed some light on this? thanks!



Boot with your live USB, open a terminal and use:



sudo apt install mkusb


Then run mkusb and create a new live USB with persistence using a new stick on a different USB port. Pay careful attention to using the correct USB port with the new USB stick.




Follow these instructions.
