I had to plough through the Ubuntu forums and combine two different responses before I could do it, though -- and the ultimate solution was far simpler than the first few pages of "all you have to do is..."
This is my biggest complaint about Linux. Open-source support is wonderful in theory -- if you do a Google search for just about any problem, you'll find a lot of people who've run into the same issue. Unfortunately, there's only a fraction of that number who can tell you how to fix it. Lots of cries for help, but very, very few rescues.
The problem I faced is apparently a common one: Fresh Ubuntu install, fresh Firefox install. Went to a page with Flash components. Got a dialogue box saying that I didn't have the right plug-in, and clicked the button to install the Adobe Flash non-free plug-in. Restarted Firefox. Went to the same page.
Got the same dialogue box.
Got a dialogue box saying that it was already installed, and I needed to restart Firefox.
Lather, Rinse, Repeat.
The first few "solutions" in the Forums explain that Adobe hasn't yet updated the DEB installer package, and list multiple different ways to assemble one from scratch.
Finally, someone says that they just found grabbed the file from Adobe, pulled the plug-in file out of the compressed bundle, and pasted it directly into Firefox's plug-ins folder. It worked for them, with no hitch, and it worked for me, to.
So, here's the Step By Step, for any desperate soul who finds Your Obedient Serpent's blog through Google:
PROBLEM: In Ubuntu 7.10, Adobe Flash Plug-In will not install properly with Firefox 2.0.
tar xvfz install_flash_player_9_linux.tar.gz
nautilus install_flash_player_9_linux(This opens a File Manager window into the directory created when you untarred the tarball in the last step.)
sudo nautilus /usr/lib/firefox/plugins(This opens a File Manager window with admin permissions into Firefox's plug-ins folder.)
libflashplayer.sofrom the first directory and psate it into the second.
- Restart Firefox.
- Laugh at those still trying to make their own DEB installers from stone knives and bearskins. A good Girl Genius Spark laugh. You know you want to.
And that's it. Download, unzip, cut, paste.
