I'm trying to install the flashplayer plugin in the three steps shown on http://www.itworld.com/software/415657/install-adobe-flash-plugin-ubuntu-1404 but get the following message: Package adobe-flashplugin is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source. E: Package 'adobe-flashplugin' has no installation cadidate.
I'm a total noobie when it comes to Linux, and I didn't bother at all with the DOS when using Windows OS, so what does this exactly mean? Can I install flash from somewhere else?
