Changing the permission on your tmp folder will resolve that, try with:

chmod -R 0777 /tmp

Run:

sudo chmod -R 0777 /tmp
sudo chmod 700 /tmp/root-states

An import process fails because the system cannot find the path specified, modify permission settings for the temporary directory that the operating system uses during the import process.

For the ubuntu os:

Run:

sudo chmod 777 /tmp
sudo chmod a+rwx /tmp

Happy coding!!!
