[Q] Trouble With Ioroot topic

I am running Ubuntu 14.04 x64. I installed the ADB packages through apt-get:

sudo apt-get install android-tools-fastboot
sudo apt-get install android-tools-adb

Then I downloaded ioroot.zip, extracted it and did:

chmod +x ioroot.sh

When I run ioroot.sh I get the following errors:

Determining device model and firmware version...
./ioroot.sh: line 93: SLEEP: command not found
./ioroot.sh: line 94: ./adblinux: Permission denied
./ioroot.sh: line 95: ./adblinux: Permission denied

Press enter to continue...

So, what does that mean?

My main goal is to root, install recovery and install Cyanogenmod.
