I read & followed along post How do I install Flash in Opera?
When I ran "sudo apt-get install adobe-flashplugin" I got
Reading package lists... Done Building dependency tree Reading state information... Done 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 candidate
Some background info: I downloaded & unzipped adobe flash PPAPI version. The readme.txt said to
Unpack the plugin tar.gz and copy all the files to /usr/lib/adobe-flashplugin/
I didnt have an adobe-flashplugin directory in /usr/lib but created one /usr/lib/adobe-flashplugin/flash and put ALL the files in there.
