UPDATE: Commenters report this as the solution:

\sudo  \apt-get  install  libcurl3:i386

The remainder of this page may also help. I have not tested this and have since abandoned this project.

Firstly, why in the motherfucking hell can I view a swf using my browser online but not use my browser offline to view an offline swf? This is madness.

I can download something, according to https://help.ubuntu.com/community/FlashPlayerStandalone

I visit was www.adobe.com/support/flashplayer/downloads.html and note that although the top of this page claims there is, there is no 64bit projector.

Tested on Lubuntu (Ubuntu 14.04.2 LTS), updated recently.

Attempting to run it gave a complaint. Every time it complained, I did something like so:

\dpkg  -S libXcursor.so.1

It would give me output like so:

libxcursor1:amd64: /usr/lib/x86_64-linux-gnu/libXcursor.so.1.0.2
libxcursor1:amd64: /usr/lib/x86_64-linux-gnu/libXcursor.so.1

One of these lines will be appropriate. Take it, and look at the left. Replace amd64 with i386 and install that. Like so:

\sudo  \apt-get  install  libxcursor1:i386

The complete list of stuff I had to install was:

\sudo  \apt-get  install \
  libglib2.0-0:i386 \
  libxt6:i386 \
  libxcursor1:i386 \
  libnss3:i386 \
  libgtk2.0-0:i386 \
` # `

However, this doesn’t work. I can launch it, but when I attempt to open a swf I get I get:

(flashplayer:3371): GLib-GObject-WARNING **: instance with invalid (NULL) class pointer

(flashplayer:3371): GLib-GObject-CRITICAL **: g_signal_handlers_disconnect_matched: assertion 'G_TYPE_CHECK_INSTANCE (instance)' failed
