Comment 294 for bug 173890

OK, here is my extremly dangerous don't-do-this-@localhost workaround:
1. Make a propoer backup of your system (I mean it!).
2. sudo bash
3. apt-get remove flashplugin-nonfree
4. cd /usr/bin/
5. mv md5sum md5sum-real
6. ln -s /bin/true md5sum
7. apt-get install flashplugin-nonfree
8. rm md5sum
9. mv md5sum-real md5sum
10. exit

This is dangerous! So don't do it!
