I have Ubuntu 12.04 64 bits. When I try to run spark 2.6.3 I get up the next error:

admini@localhost:~/Spark$ sh starter 
Preparing JRE ...
starter: 150: starter: bin/unpack200: not found
Error unpacking jar files. Aborting.
You might need administrative priviledges for this operation.

in version 11.10 running smoothly. Not sure what is happening.

I think you need to be root to run that. try sudo -s your password then run the script – user82356 Aug 9 '12 at 17:01

If you are using 64bit Ubuntu you need to install the ia32-libs Install ia32-libs library that the spark for work, to install in a terminal type
sudo apt-get install ia32-libs
restart the system and finally enter the directory where you installed Spark and the necessary permissions to read and execution totos users I gave permission
sudo chmod 777 Spark
but the permissions you see fit. Worked with me.

Worked for me after installing openjdk-6-jre:i386 and icedtea plugin (but I don't know if that's really necessary)

Let me know if that helps!

I ran this and it helped me:

mv jre jre.not sed -i 's/\/lib\/windows/\/lib\/linux/g' Spark/Spark
