Hi!! I am new to OpenFOAM, and I want to get it set up before the beginning of next semester. I am following the instructions on:
http://www.openfoam.org/archive/2.1....oad/ubuntu.php

It seems to be going well, until I have to modify the bashrc file, since I can't open it from the terminal, and if I open it manually, I'm not able to add the line "source /opt/openfoam211/etc/bashrc" at the end of the file (saying I don't have permission to do so).

ruben@ruben-VirtualBox:~$ VERS=$(lsb_release -cs)       
ruben@ruben-VirtualBox:~$ sudo sh -c "echo deb http://www.openfoam.org/download/ubuntu $VERS main > /etc/apt/sources.list.d/openfoam.list"
ruben@ruben-VirtualBox:~$ sudo apt-get update

Any idea of what am I doing wrong? Suggestions?
To those who read this, happy new year 2014!

Greetings Ruben and welcome to the forum!

Many thanks for sharing the output from your command line, along with a detailed description, since that makes it a lot easier to figure out what's going on!

The first issue might be that gedit from the command line doesn't work very well when Ubuntu is using the Unity desktop

If you don't have permissions to edit the file "~/.bashrc", when you browse manually with the text editor, it might be due to one of the two possible situations:

1. The file "~/.bashrc" is the same as "$HOME/.bashrc", so if you run:
   

   echo $HOME/.bashrc

   You'll see the correct path. If the file on that path is not the file you are trying to edit, than that's the problem.
2. The other possibility is if you edited the correct file, but while using the sudo command, which might have changed the ownership of the file. If this is the case, run:
   

   sudo chown $USER:$USER ~/.bashrc

   This will return the ownership to your user-name. Now you can edit the file with the "Text Editor".

Best regards,
Bruno

Thanks for such a quick reply, and sorry for my late response. Tried your solution last week and was busy packing and sorting other things.

What you proposed actually worked! I went with the change of ownership, was able to run the "icoFoam -help" , run a project and view it in paraFOAM

I'll be starting my thesis project next week, so I guess there will be more questions coming up in the future!

Greetings from Copenhagen
