operation not permitted in `disc`

[hkousha]

Just installed mylg using download link in the website on Ubuntu 16.10 .

When I run disc I get the messages Operation not permitted. I tried running it as sudo and also as an admin user, same result:

✗ 14:35:14 kousha-ubuntu:kousha ~/Downloads% sudo mylg 
[sudo] password for kousha:
