Enable Universe and Other Repositories

Search for ‘software’ and click at ‘Software and Updates’. Check to enable repositories from ‘Ubuntu Software’ and ‘Other Software’ tabs. The partner repositories are source of software with restricted license so that the general public can not simply share them, such as Flash and Skype. These are official repo’s that are already added but disabled in Ubuntu.
