flash plugin not working in chromium and mozilla, on ubuntu
 

downloaded flash plugin from terminal by,
sudo apt-get install flashplugin-installer

then made a directory by,
sudo mkdir opt/google/chromium/plugins

then tried to copy to opt/google/chromium/plugins, by
sudo cp /usr/lib/flashplugin-installer/libflashplayer.so /opt/google/chromium/plugins

but the terminal prompts a message...
cp: cannot create regular file `/opt/google/chromium/plugins': No such file or directory.

want to install it, any ideas why this is happening

The above command probably needs the -p option,

Not sure why you are doing all this with chromium as its in the repos with flash,

Not the correct package name on Ubuntu.

But it also shouldn't need any other steps.

Whoops, my bad. That should be,

and what command will be needed to copy flash installer to /opt/google/chromium/plugins
i did this
sudo cp /usr/lib/flashplugin-installer/libflashplayer.so /opt/google/chromium/plugins

and the terminal prompts this
cp: cannot create regular file `/opt/google/chromium/plugins': No such file or directory

How To Install Flash Plugin In Chromium For Ubuntu | THEGEEKIN • Still What - http://stillwhat.com/install-flash-p...romium-ubuntu/

Or just install Chrome since it comes with flash and will soon be the only way to get Adobe Flash.

It is funny people will use a non-free proprietary plugin like Adobe Flash but will not use Google Chrome.

fixed...... if ur youtube videos are not working even after installing flash player

Then, open up a YouTube video, right-click on the video itself and click on Settings.
Uncheck the "Enable hardware acceleration" checkbox in the Display tab.

this should work, it worked for me

Quite true in a way. You probably double the non-free sin with Chrome though.

Hurray for the OP and working Flash!
 

To the OP glad you finally got it working! :)

Google Chrome, adobe Flash, oracle's Java 7, and to top it off using Google's DNS.
$ apt-cache policy google-chrome-stable
google-chrome-stable:
Installed: 19.0.1084.56-r140965

Reminds self to go check Java, Oracle was supposed to releases fixes today.
$ java -version
java version "1.7.0_04"
Java(TM) SE Runtime Environment (build 1.7.0_04-b20)
Java HotSpot(TM) Client VM (build 23.0-b21, mixed mode)

$ cat /etc/resolv.conf
nameserver 8.8.8.8
nameserver 8.8.4.4


I also use Firefox with the same. I run Debian because it works, not because I am a Stallman/FSF zealot.

Do you run FreeBSD on the quiet :)
