How To Fix “Permission Denied” Error When Installing Intel Fortran Composer 2011 on Ubuntu

In this article, we will discuss a common issue faced by users when installing Intel Fortran Composer 2011 on Ubuntu: the “Permission Denied” error. This error typically arises due to a lack of necessary permissions to execute the installation script. We will provide a step-by-step guide on how to resolve this issue.

Understanding the “Permission Denied” Error

The “Permission Denied” error occurs when the system restricts the execution of a command due to insufficient permissions. In the context of installing Intel Fortran Composer 2011, this error is often encountered when trying to run the installation script without the necessary administrative (or root) privileges.

Solution 1: Execute the Script with Root Privileges

One of the simplest ways to resolve this issue is by executing the installation script with root privileges. To do this, you will need to use the sudo command, which stands for “superuser do”. This command allows you to run programs with the security privileges of another user (by default, the superuser or root).

Here’s how you can do this:

1. Open a terminal.
2. Navigate to the directory where the install.sh script is located.
3. Run the command: sudo bash install.sh

The sudo command elevates your permissions, allowing you to run the script as the root user. bash is the command that executes the script, and install.sh is the script itself.

Solution 2: Change the Permissions of the Script

If running the script with root privileges does not resolve the issue, you can try changing the permissions of the script to make it executable. This can be done using the chmod command, which stands for “change mode”. This command is used to change the permissions of a file or directory.

Here’s how you can do this:

1. Open a terminal.
2. Navigate to the directory where the install.sh script is located.
3. Run the command: chmod +x install.sh
4. Then, try running the script again using ./install.sh.

The +x parameter adds the executable permission to the file, allowing it to be run as a program.

Solution 3: Specify the Full Path to the Script

In some cases, you may need to specify the full path to the script when running it. This can be necessary if the script is not located in the current directory.

Here’s how you can do this:

1. Open a terminal.
2. Run the command: sudo /path/to/install.sh

Replace /path/to/install.sh with the actual path to the script.

Solution 4: Check the File Location and Name

Lastly, ensure that the install.sh file is located in the current directory or the specified path. Also, double-check the spelling and capitalization of the file name. Linux file systems are case-sensitive, so install.sh and Install.sh would be treated as different files.

Conclusion

If none of the above solutions work, there may be other issues with the installation process or the script itself. In such cases, it is recommended to consult the Intel Fortran Composer 2011 documentation or seek assistance from the Intel support team for further troubleshooting. Remember, understanding the cause of the error is the first step in resolving it.
