When I play online videos, they are often interrupted with many blinks and other disturbances. Many times I was shown an error message that the flash player crashed. When I tried to install the flash plugin on the command line, this error was displayed. Can anyone help me to get out of this conflict?

$ sudo apt-get install flashplugin-installer

[sudo] password for agha:

E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' 

 to correct the problem
