I am having a trouble with my adobe flash. I am using Firefox on my Ubuntu system. My adobe flash doesn't enable on any of the web videos(See Pic_1).
So when I go to the official website to download the newer version of it (See Pic_2).
After I finished the downloading, it gave me this error message (See Pic_3).
I have tried sudo apt-get upgrade on the terminal. It is still not working...
What can I do? I would really appreciate if someone can help!
I'm not familiar with the error message you're receiving. Appears to be something specific to the site.
