I installed Ubuntu from the Parallels control panel. Since starting Ubuntu for the first time, I get the message that the Parallels tools are out of date and to manually install. I have opened the disk image on the Ubuntu desktop and clicked the install button, have tried both Run and Run from Command Line with no success. I know nothing about Ubuntu or Linux. Where to I go to find the updated tools and how do I install them? Also, the automatic update in the lower right of the status bar doesn't do the job, either.
