[SOLVED] Install Pepper Flash Player For Chromium In Ubuntu Via PPA

For what it is worth: you can put the whole thing in a terinal to open the file directly in the text editor, like so:

gksu gedit /etc/chromium-browser/default

You can install pepperflash without it.
Simply open the program called Software and Updates,
go to the section marked Other Software
Enable (check) the Canonical Partners.
Close Software and Updates.
And if it ask to reload, let it.
(If it does not ash to reload, run:

sudo apt-get update

Hope it helps.
