In a fresh installed or upgraded Ubuntu, first thing to do is install flash plugin for web browser to enjoy flash videos. As a beginner, we use Ubuntu Software Center to search and install applications.
In Ubuntu 11.10, the Ubuntu Software Center shows two:
Adobe Flash Plugin 10 and
Adobe Flash Plugin. I selected
Adobe Flash Plugin 10. But after installation, both Firefox and Google Chrome were still not working, even there’s no adobe flash plugin showing in
May be the second choice work, I didn’t try. I finally use the following method get the flash working in my 64-bit Ubuntu 11.10 Oneiric:
First, in a terminal window remove old, unnecessary packages:
sudo apt-get remove --purge adobe-flashplugin flashplugin* nspluginwrapper
Reinstall the flash:
sudo apt-get install --reinstall adobe-flashplugin
Now, restart your browser and it should work.
