Hello, now I’m using rosbot2.0(OS: ubuntu 16.04) and want to upgrade from 16.04 to ubuntu18.04.
I tried to this instruction but It doesn’t working.
i guess data is broken. because i modify file.
so i think that the existing operating system(ubuntu16.04) have to be deleted and new OS will be installed.
I would appreciate it if you tell me how to install and delete it
