How To Fix the “/lib/modules/3.13.0-27-generic/build: No such file or directory” Error in Ubuntu?

Ubuntu 1

When working with Ubuntu, you may occasionally encounter the error message “/lib/modules/3.13.0-27-generic/build: No such file or directory”. This error typically arises when the appropriate Linux headers for your kernel version are missing. This article will guide you through several methods to resolve this issue.

Understanding the Error

Before we delve into the solutions, it’s important to understand what the error message means. The “/lib/modules/3.13.0-27-generic/build” path is a symbolic link that points to the Linux headers directory. If the headers are missing, the symbolic link ends up pointing to a non-existent directory, causing the error.

Method 1: Install the Specific Linux Headers Package

The first method to resolve this issue is to install the specific Linux headers package that matches your kernel version. In this case, the package would be linux-headers-3.13.0-27-generic. You can install this package using the apt-get install command:

sudo apt-get install linux-headers-3.13.0-27-generic

The sudo command is used to execute the following command with root privileges. apt-get install is used to install packages, and linux-headers-3.13.0-27-generic is the package name.

Method 2: Install the Linux Headers for Your Current Kernel Version

If the specific Linux headers package is not available, you can install the Linux headers for your current kernel version dynamically. This can be done using the uname -r command, which returns the current kernel version:

sudo apt-get install linux-headers-`uname -r`

Here, the backticks () around uname -r` execute the command and replace it with its output, effectively installing the Linux headers for your current kernel version.

Method 3: Update Your System

In some cases, updating your system and upgrading your installed packages can resolve the issue. You can do this using the apt-get update and apt-get dist-upgrade commands:

sudo apt-get update && sudo apt-get dist-upgrade

The && operator is used to run the second command only if the first command completes successfully. apt-get update updates the list of available packages and their versions, while apt-get dist-upgrade upgrades the currently installed packages and their dependencies.

Method 4: Install the “linux-generic” Package

If none of the above methods work, you can try installing the “linux-generic” package. This package installs the latest possible kernel for your Ubuntu distribution:

sudo apt-get install linux-generic

Method 5: Manually Locate the Correct Headers

As a last resort, you can manually locate the correct headers using the find command:

find / | grep include/generated/autoconf.h

This command searches for the “autoconf.h” file, which is typically found in the Linux headers directory. Once you find the correct directory, replace the /lib/modules/$(uname -r)/build path in the Makefile with the result from the previous command.

Conclusion

Resolving the “/lib/modules/3.13.0-27-generic/build: No such file or directory” error in Ubuntu involves installing the appropriate Linux headers for your kernel version. This can be done by installing the specific Linux headers package, installing the Linux headers for your current kernel version, updating your system, installing the “linux-generic” package, or manually locating the correct headers. By following these methods, you should be able to resolve the issue and continue working with Ubuntu without interruption.

What does the error “/lib/modules/3.13.0-27-generic/build: No such file or directory” mean?

This error message indicates that the Linux headers directory for your kernel version is missing, resulting in a broken symbolic link.
