Ultimo theme installation issue

Hey guys,
I hope some one help me to solve my problem. When I was running php bin/magento setup:upgrade command in SSH for enabling the Ultimo theme modules, there is a strange message came up like " The directory ‘/home1/atuxadem/public_html/var/di’ doesn’t exist-skipping cleanup" . I searched online and some one suggested to change file permissions, and I did so. However, the problem still wasn’t be solved. I contacted the host provider and they said it’s not possible using SSH to install the theme, but the theme developer was recommending to use the SSH network transfer application. There are some people have facing same problem, but they didn’t say if it’s solved. Please share your knowledge with us, and it will be really appreciated. Thanks in advance.
Best regards,

I could offer some paid support, if you’re interested in

or you can purchase the installation service:
