How do I install Flash in Opera? [duplicate]

Solution 1:

There're multiple conflicting packages, e.g. flashplayer-mozilla, flashplugin-installer, adobe-flashplugin…

The specific one you need for Opera browser is adobe-flashplugin, i.e.

sudo apt-get install adobe-flashplugin

Update per comments: if you get a has no installation candidate error, run software-properties-gtk, and set all checkboxes on the Ubuntu Software tab. Next update packages list with, e.g., sudo apt-get update, and try installing again.

Solution 2:

That help page is seriously outdated: “This document was last updated for Opera 11.00” while the current version is 41 and Opera completely switched the rendering engine to Blink (the same as in Chromium/Chrome) in the mean time.

If you look at the packages recommended by the opera-stable package, you'll find an entry for pepperflashplugin-nonfree. This package will install the PPAPI Flash Player plug-in included with Google Chrome which will work with Opera too (otherwise they wouldn't suggest it).

Furthermore, the more recent releases of the adobe-flashplugin include the same PPAPI Flash Player without the detour through Google Chrome. You can install it as in How to install Flash player on Ubuntu?. Use karel’s answer if you're unsure since that's the recommended way to install Flash Player in Ubuntu these days, which happens to recommend the same as Hi-Angel’s answer here.
