Install Flash on Chromium OS

flashinst.sh

# INSTRUCTIONS:
 
# Enter the terminal (Ctrl-Alt-F2, username is "chronos" and password is either blank or "password" for ArnoldTheBat's builds) and run:
#
# curl -L https://goo.gl/BBV79Q | sudo bash
#
# to install. You'll likely have to re-enter the password "password".
# Attempts to grab the latest Flash version straight from Adobe's website.
# Should be a bit more bullet-proof than some of the other flash installer scripts.

# NOTE: If you can't enter the terminal, follow step 5 from: https://gist.github.com/balupton/9908197

Hello, thanks for working on this. When I try to run the script, I get the error "gzip: stdin: not in gzip format tar: child returned status 1 tar: Error is not recoverable: exiting now"

Is there something that I'm missing in order to get this running?

i get the same error. Please help!

Works great, except for downloading the flash player itself. For some reason that part doesn't work anymore, so I had to download it manually by going to https://get.adobe.com/flashplayer/otherversions/ and selecting Linux 64bit and the .tar.gz PPAPI version.
Then instead of the curl -sL ... just put cat /home/user/...../Downloads/flash_player_....tar.gz.
Tried on Chromium OS 64.
