I fixed 64 bit Flash on my 11.10 systems without any wrappers. In the interim - either use the first 'Multiverse' 32bit plugin in the pictures above or use adobe-flashplugin sudo apt-get install adobe-flashplugin

Note - pictures subject to change - the 64bit version has only been recently packaged in the last week before Oneiric release - One issue currently exists: Right click and confirm that the latest version of Flash has been installed correctly.

Once complete - launch Firefox and browse to your Flash Video. Note - you must have permission to install software. See the end of this answer for the bug-reportĬlick the Install button and enter your password when prompted. and click Use this source to enable the Canonical Partner Repository

Select the second flash entry - if the following picture is seen then you have not already enabled the Canonical Partner Repository previously. The first is the wrapper around the 32bit flash version from Adobe.

Start Software Center from the Launcher and search for flash
