Understanding the version of Ubuntu running on your system is essential for various reasons, such as ensuring compatibility with software packages and keeping your system up-to-date. In this article, we’ll explore multiple methods to check the Ubuntu version.
Method 1: Using the lsb_release Command: The lsb_release command is a straightforward way to obtain detailed information about the Ubuntu distribution.
Open a terminal and enter the following command:
lsb_release -a
This will display information such as the Distributor ID, Description, Release number, and Codename. The “Description” field will specify the Ubuntu version.
Method 2: Checking the /etc/os-release File: The /etc/os-release file contains key information about the operating system, including the version.
Execute the following command to view the contents of the file:
cat /etc/os-release
Look for the VERSION_ID field, which explicitly indicates the Ubuntu version.
Method 3: Checking the /etc/lsb-release File: Similar to the /etc/os-release file, /etc/lsb-release provides distribution information.
Use the following command to view its contents:
cat /etc/lsb-release
Look for lines such as DISTRIB_ID=Ubuntu, DISTRIB_RELEASE, and DISTRIB_CODENAME to identify the version.
Method 4: Checking the /etc/issue File: The /etc/issue file typically contains information about the distribution and version.
Execute the following command:
cat /etc/issue
Information like “Ubuntu 20.04.3 LTS \n \l” can help identify the version.
Method 5: Using the uname Command: While not specific to Ubuntu version, the uname command provides general information about the system, including the Linux kernel version.
Enter the following command:
uname -a
Look for details such as the Linux version and build date.
Conclusion: Knowing the version of Ubuntu on your system is crucial for effective system management. Whether you prefer the lsb_release command or exploring system files, these methods provide you with the necessary information to identify the Ubuntu version with ease. Regularly checking and updating your system ensures optimal performance and compatibility with the latest software releases.
