Goal is to share clipboard between Ubuntu 14 VM and OSX Yosemite. According to the How to install Parallels Tools in Linux virtual machine support page (referred to from Clipboard Support in Ubuntu lacking Friendliness), you need to run su. It asks for a password. I have to created any other users so I assume it's the same as the paralles@ubuntu user. However, when I enter that password I get su: Authentication failure. How can I get su working so I can update Parallels Tools in Ubuntu so I can get copy and paste working?
