Symptoms

Unable to install mod_perl, SpamAssassin or other Plesk component. The following errors are returned:

Traceback (most recent call last):
File "/usr/local/psa/bin/yum_install", line 239, in <module>

File "/usr/local/psa/bin/yum_install", line 225, in main
raise Exception("Failed to solve dependencies:n" + 'n'.join(msgs))
Exception: Failed to solve dependencies:
glibc-headers-2.17-157.el7_3.5.x86_64 requires kernel-headers >= 2.2.1
glibc-headers-2.17-157.el7_3.5.x86_64 requires kernel-headers
Error: The Yum utility failed to install the required packages.

Cause

kernel-headers package is missing or version is lower than 2.2.1.

Resolution

1. Connect to the server via SSH.

2. Check kernel version:

   # uname -r

3. Check if matching kernel headers are already installed on your system:

   # ls -la /usr/src/kernels/

4. If no matching kernel headers are found in that directory, install kernel headers with yum command as follows:

   # yum install kernel-devel

5. Add required Plesk component again.
