I have never installed Mathematica, but I would start by looking at the file listed in the error output:

/usr/local/Wolfram/Mathematica/6.0/InstallErrors

Look at this file with something like Gedit or


less /usr/local/Wolfram/Mathematica/6.0/InstallErrors

This will probably tell you more.

It also looks like you are acting as root. What process did you use to "become" root. I usually just do everything through sudo which is typically the "ubuntu way" of doing things.

aprasanth,
I installed Mathematica a few months ago and got a similar message, on contacting Wolfram support the following advice was given :

There are two things you need to check:
1. Check you have installed libstdc++5 by typing:
sudo apt-get install libstdc++5

2. If you go to /usr/local/bin (default directory) and see Mathematica
scripts are there, that means installation is complete. Please type ./math
under this directory and you should be asked to enter license number,
organization and password. Please go to http://register.wolfram.com to
register your information to acquire the valid password.

I hope that this is of help.

Best regards,
cpgos

I installed mathematica only a few days ago... cpgos is correct. You need libstdc++5 installed.
