ET on Ubuntu 64-bit

Trying to install Enemy Territory - Return to castle Wolfenstein on a 64-bit Ubuntu installation? I ran into 2 problems, and this is how I solved them:

• This installation doesn't support glibc-2.0 on Linux / unknown
  (tried to run setup)See http://zerowing.idsoftware.com/linux/ for troubleshooting
  The setup program seems to have failed on unknown/glibc-2.0
  This problem can easily be solved by running the installer with "linux32 sh /path/to/et-linux...x86.run"
• The other problem was that there wasn't any sound, and ET displayed this error: Could not mmap /dev/dsp. The solution is running this (as root) before you start ET (you have to do this only once, until you reboot):
  echo "et.x86 0 0 direct" > /proc/asound/card0/pcm0p/oss
