How to Know the Version of Linux
Linux is an open-source operating system that has been around for over two decades. With so many distributions (distros) available, it can be overwhelming to know which one to use. In this article, we will guide you through the process of identifying the version of Linux on your system.
Understanding Linux Versions
Linux versions are typically represented by a combination of letters and numbers. The most common version numbers are:
- Ubuntu: 20.04 (Focal Fossa)
- Debian: 10 (Buster)
- Fedora: 35 (Core)
- CentOS: 8 (Stream)
- Red Hat Enterprise Linux: 8 (Stream)
Identifying the Version of Linux on Your System
To identify the version of Linux on your system, follow these steps:
-
Check the Package Manager: The package manager is the tool that manages software packages on your system. Most Linux distributions use the package manager to install, update, and remove software. The most common package managers are:
- Ubuntu: apt (Advanced Package Tool)
- Debian: apt (Advanced Package Tool)
- Fedora: dnf (Diet Linux)
- CentOS: yum (Yellow Dog Linux)
- Red Hat Enterprise Linux: yum (Yellow Dog Linux)
-
Check the System Information: You can check the system information by running the following command:
- Ubuntu:
lsb_release -a - Debian:
dpkg -s - Fedora:
dnf info - CentOS:
yum info - Red Hat Enterprise Linux:
yum info
- Ubuntu:
- Check the System Logs: You can check the system logs by running the following command:
- Ubuntu:
journalctl - Debian:
journalctl - Fedora:
journalctl - CentOS:
journalctl - Red Hat Enterprise Linux:
journalctl
- Ubuntu:

Here are some significant Linux versions to keep in mind:
- Ubuntu 16.04 (Xenial): This version was the first to use the Linux kernel 4.x.
- Ubuntu 18.04 (Bionic): This version was the first to use the Linux kernel 4.15.
- Ubuntu 20.04 (Focal Fossa): This version was the first to use the Linux kernel 5.x.
- Debian 9 (Buster): This version was the first to use the Linux kernel 4.15.
- Debian 10 (Buster): This version was the first to use the Linux kernel 5.x.
Other Linux Versions
Here are some other significant Linux versions to keep in mind:
- Fedora 32: This version was the first to use the Linux kernel 5.x.
- CentOS 8: This version was the first to use the Linux kernel 5.x.
- Red Hat Enterprise Linux 8: This version was the first to use the Linux kernel 5.x.
Troubleshooting
If you are having trouble identifying the version of Linux on your system, here are some troubleshooting steps:
- Check the Package Manager: Make sure the package manager is installed and up-to-date.
- Check the System Logs: Check the system logs for any error messages that may indicate the version of Linux.
- Check the System Information: Check the system information for any information that may indicate the version of Linux.
Conclusion
Identifying the version of Linux on your system can be a bit tricky, but following these steps can help you to do so. By checking the package manager, system information, and system logs, you can determine the version of Linux on your system. Additionally, checking the significant Linux versions can help you to understand the history and development of the Linux operating system.
