How do I install Adobe Flash player?
Why does it always say “Requires Installation of Untrusted Packages” and not let me download?
I am new to this and could really use some help. I have tried looking online but I don't understand what I need to do to fix this. My knowledge is very basic. Help would be greatly appreciated.
I have this same problem on my machine, but it happens when I try to install anything. The workaround I use is to install the application through the terminal instead. Open a terminal (ctrl + alt + T) and run the following command: sudo apt-get install flashplugin-installer. Enter your password when prompted, then answer 'y' to the next two prompts. After the program downloads and installs flash player you can close the terminal. Hope that helps!
