  • Distribution-Specific Issues: Certain distributions may have different naming conventions or may not support `libmnl-devel`.

Steps to Resolve the Issue

  1. Check Repository Configuration:
  • For RHEL/CentOS:
  • Ensure that the EPEL repository is enabled:

“`bash
sudo yum install epel-release
“`

  • For Fedora:
  • Use the DNF command to check repository status:

“`bash
dnf repolist
“`

  1. Search for the Correct Package Name:
  • Use the following command to search for the package:

“`bash
yum search libmnl
“`

  • This command will provide a list of available packages related to `libmnl`.
  1. Update Package Index:
  • Refresh the package index with:

“`bash
sudo yum clean all
sudo yum makecache
“`

  1. Install Alternative Packages:
  • If `libmnl-devel` is not found, consider installing related packages:

“`bash
sudo yum install libmnl
“`

  • Check if the package is available in a different repository or under a different name.

Verifying Installation

After attempting the installation, verify if the package has been successfully installed:

  • For RHEL/CentOS:

“`bash
rpm -qa | grep libmnl
“`

  • For Debian-based systems:

“`bash
dpkg -l | grep libmnl
“`

Command Description
`yum search libmnl` Searches for libmnl packages
`rpm -qa grep libmnl` Lists installed libmnl packages
`dnf repolist` Displays enabled repositories

Alternative Installation Methods

I didn’t start out in tech with a clear path. Like many self taught developers, I pieced together my skills from late-night sessions, half documented errors, and an internet full of conflicting advice. What stuck with me wasn’t just the code it was how hard it was to find clear, grounded explanations for everyday problems. That’s the gap I set out to close.

Freak Learn is where I unpack the kind of problems most of us Google at 2 a.m. not just the “how,” but the “why.” Whether it's container errors, OS quirks, broken queries, or code that makes no sense until it suddenly does I try to explain it like a real person would, without the jargon or ego.
