I just installed Ubuntu today and I went to the Ubuntu software center to install Adobe Flash player.

And when the install button is pressed, I received the following message:

Package dependencies cannot be resolved

This error could be caused by required additional software packages which are missing or not installable. Futhermore there could be a conflict between software packages which are not allowed to be installed at the same time.

Please help me.

Have you closed all your other programs before open the Software-Center? – Lucio Sep 17 '12 at 20:19
Which Ubuntu version? In terminal, do sudo apt-get update work without errors? – Noble P. Abraham Sep 18 '12 at 4:44

OK, if you just installed Ubuntu you have Mozilla Firefox. Try using the Flash-Aid add on:

Good luck.
