I think his point was that he followed the instructions, and they failed. If he had been using Windows, he'd have followed the instructions and succeeded. This is the problem with Linux.
FWIW, I currently run Ubuntu on my laptop, and very much like it, Windows 7 on my work desktop, and my previous laptop ran OSX.
Is this the first time you've circumvented the package management system? If you have done it before, maybe that's the cause of the pain now? Just guessing, since these things usually work without any complaint for me.
It would be funny --- if it wasn't so tragic --- how much easier to use and manage free software is. Especially considering it's almost all just './configure ; make && make install' at the base level.
Not that you are one, but it's funny to watch Linux fanboys run into trouble with tasks that should be simple. It of course doesn't diminish their opinion of Linux being the greatest desktop by far.
- Firefox asked me whether I wanted to launch the 'apturl' tool. I accepted its suggestion.
- I got a dialog saying "This will enable the Canonical Partners repository". I'm pretty sure I already had it enabled, but sure, what the hell.
- I got the usual 'downloading updated package lists' dialog.
- I got an error dialog complaining that 'adobe-flashplugin' is a purely virtual package.
And that was that.
Guess it's back to trusty ol' tarballs.
