I have Chromium web browser on my Lubuntu 13.04 (pre-installed).

I use LX Terminal (pre-installed) to write commands.

I am trying to download flash player on Chromium using instructions on this site :

sudo add-apt-repository ppa:skunk/pepper-flash

After typing in my password, this worked. Now

sudo apt-get update

I didn't need to type in my password, as I continued on the same terminal, but got W:/ and E:/ fetch file errors

sudo apt-get install pepflashplugin-installer

I continued on the same terminal despite the fetch file errors... and they said pepflashplugin-installer could not be found.

Is the last error because of fetch file errors, or because I need to download pepflash-plugin-installer somewhere? Or is it because of something else?

I cannot download the Chrome browser, and not looking to use flash player on my Firefox web browser (installed using lubuntu software centre).
