[Solved] I want to upgrade ubuntu18.04(rosbot2.0)

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.
sudo do-release-upgrade

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

Hello prejudge,

You can install new system by following system reinstallation guide:

Please keep in mind that this will delete all your data from ROSbot. If you have any projects that you wish to use on new system, you need to copy that data on other device before the system reinstallation.

Regards,
Łukasz
