Title:
  Flash not working after upgrade from 10.04 (Lucid) to 12.04 (Precise)
  because of bad librtmp.so.0 location

Status in “rtmpdump” package in Ubuntu:
  Fix Released

Bug description:
  Flash was not working (neither in Firefox nor in Chromium) after
  upgrading my laptop from 10.04 (Lucid) to 12.04 (Precise). It would
  just display a black box in place of the flash content, also this
  content box would immediately display garbled output if you scrolled
  the page (i.e: you would see the content of the previously loaded
  content in that pixel area but no flash content at all). Right-
  clicking the flash box showed that the plugin was indeed recognized
  ("About Adobe Flash Player 11.2.202.243") but a grayed-out option
  would show "Movie not loaded". The same problem with happened with
  Chromium and with previous versions of Flash, only Flash 9 worked but
  it would not play any sound.

  After spending more than 30 hours troubleshooting this issue, I
  eventually figured out the problem. Comparing the strace output from
  my upgraded 12.04 installation (which didn't work) to the strace
  output from a live 12.04 USB stick (which did work), I eventually
  noticed that my upgraded output was not finding the librtmp.so.0
  library:

  In 12.04 Live:
  4325  open("/usr/lib/i386-linux-gnu/librtmp.so.0", O_RDONLY|O_CLOEXEC) = 18

  In 12.04 upgraded from 10.04:
  6213  open("/lib/i386-linux-gnu/librtmp.so.0", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
  6213  open("/usr/lib/i386-linux-gnu/i686/sse2/librtmp.so.0", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
  6213  open("/usr/lib/i386-linux-gnu/i686/cmov/librtmp.so.0", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
  6213  open("/usr/lib/i386-linux-gnu/i686/librtmp.so.0", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
  6213  open("/usr/lib/i386-linux-gnu/sse2/librtmp.so.0", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
  6213  open("/usr/lib/i386-linux-gnu/librtmp.so.0", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
  6213  open("/lib/librtmp.so.0", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
  6213  open("/usr/lib/sse2/librtmp.so.0", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
  6213  open("/usr/lib/librtmp.so.0", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)

  Then I noticed that my upgraded 12.02 had librtmp.so.0 in a path that
  is not being searched by Firefox/Flash:

  -rw-r--r-- 1 root root 100224 Jan 11  2012 /usr/lib/i486-linux-
  gnu/librtmp.so.0

  The problem was then easily solved like this:

  sudo cp /usr/lib/i486-linux-gnu/librtmp.so.0 /usr/lib/i386-linux-
  gnu/librtmp.so.0

  ...and also googling around I found that a similar issue is described in launchpad bug #982436 affecting pycurl:
  https://bugs.launchpad.net/ubuntu/+source/pycurl/+bug/982436

  I hope you can fix the underlying issue by either copying librtmp.so.0
  to the correct location or adding the /usr/lib/i486-linux-gnu/ to the
  default library paths.
