@parentibule you messed up something, I see you are running commands from an home directory of an user named 'm1_2.1'. Have you intentionally did this or you were just trying to put nvOC into a different folder? If you know how Windows users profile works, you know that there exist a folder for each user in C:\Users\ for example my user folder is C:\Users\LuKe. In Ubuntu that is the same thing but every user has a folder inside the /home directory, so in nvOC images the default user is 'm1', therefore exists a folder /home/m1 which is the place where all user files need to be. If you created a new user named 'm1_2.1' then it is correct that such /home/m1_2.1 folder exists, but in such a case you did a horrible choice in placing nvOC files inside his home folder because Ubuntu uses that folder to store all system files related to that user, that's why the default location for nvoc files in prebuilt images is '/home/m1/NVOC/something', /home/m1 is the home folder for m1 user, NVOC is just a folder like any other. If, instead, you choosed to place nvOC files inside an arbitrary folder name /home/m1_2.1 but you created no user named m1_2.1 then you did a mistake, reinstall nvOC into another folder. Remember that the default m1 user is a NOPASSWD sudoer, he can reboot doing 'sudo reboot' without being asked for credentials. Don't care the nvOC as a service mode, it is an alternative to gnome for who really needs it.
