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).
