I was installed successfully various dependencies according to the course instructions up to removal of modemmanager and make new directory courseRoot.
However, after I executed the next steps with the commands:
nghiale@nghiale:~$ sudo echo “export courseRoot-/home/$USER/courseRoot” >> ~/.bashrc
and source it with:
nghiale@nghiale:~$ source .bashrc
It seemed like there is no problem. However, when I followed the video instruction to access courseRoot with the following command:
nghiale@nghiale:~$ cd $courseRoot
and my system returned the following prompt:
instead of the prompt with home directory and my usename (nghiale) as the $USER (as indicated in the video):
I don’t know why. Did I do something wrong?
I think this problem also prevented me from executing successfully later a submodule update command, i.e.
$ git submodule update --init --recursive
which I will submit later if I am not able to resolve it.
