unable to install libflashplayer.so

Moving to Flash...converting to question

Thank you for taking the time to report this issue and helping to make Ubuntu better. Examining the information you have given us, this does not appear to be a bug report so we are closing it and converting it to a question in the support tracker. We appreciate the difficulties you are facing, but it would make more sense to raise problems you are having in the support tracker at https://answers.launchpad.net/ubuntu if you are uncertain if they are bugs. For help on reporting bugs, see https://help.ubuntu.com/community/ReportingBugs#When%20not%20to%20file%20a%20bug.

The correct way to install Flash on Ubuntu is to install the flashplugin-installer package using your package manager (Synaptic, Adept, aptitude).

You dont run that file, that file IS the plugin.

If you run:

sudo apt-get install flashplugin-nonfree

it will install the plugin. If you use a 64bit Ubuntu (check using: uname -a | grep i686 if you get an output its 32bit, if you don't its 64bit)

If it is 54bit (no output from above commad) you can use the 64bit plugin using this command (i'll assume you use firefox like all the other users):

mkdir ~/.mozilla/plugins; cd ~/.mozilla/plugins; wget http://download.macromedia.com/pub/labs/flashplayer10/libflashplayer-10.0.32.18.linux-x86_64.so.tar.gz; tar zxvf ./libflashplayer-10.0.32.18.linux-x86_64.so.tar.gz; rm ./libflashplayer-10.0.32.18.linux-x86_64.so.tar.gz

If you use this you CANNOT have ANY other falsh packages installed. You can check with:

dpkg -l | grep flash; dpkg -l | grep gnash; dpkg -l | grep swf

If you like I can give a command to remove them as well.

If your OS is 32bit (output from the uname command happened) then you can install flashplugin-nonfree and get 32bit flash. flashplugin-nonfree WILL work on 64bit Ubuntu but will be 32bit flash running via an abstraction layer called nspluginwrapper.
