About 'Adobe Flash plugin' in software center
I am trying to download Adobe Flash and I am new to Linux and Ubuntu. Help.
see this answer here for details http://askubuntu.com/a/115308/46312
There are two packages for installing flashplugin. The packages are called flashplugin-installer and adobe-flashplugin
Alternatively, you can download the tar.gz directly from http://get.adobe.com/it/flashplayer/ and put it in the right plugin folder (i.e. for mozilla ~/.mozilla/plugins/)
