  • How to check Ubuntu version

    Below you can find some tips on how to check Ubuntu version you are currently running. The first place to look for Ubuntu version is to look inside /etc/issue file. From terminal run command:

    $ cat /etc/issue
    Ubuntu Xenial Xerus 
     l


    To obtain a Ubuntu release number check content of /etc/lsb-release file:
    $ cat /etc/lsb-release 
    DISTRIB_ID=Ubuntu
    DISTRIB_RELEASE=16.04
    DISTRIB_CODENAME=xenial
    DISTRIB_DESCRIPTION="Ubuntu Xenial Xerus
    


    Additional information regarding Ubuntu version can be found within /etc/os-release:

    $ cat /etc/os-release 
    NAME="Ubuntu"
    VERSION="16.04 (Xenial Xerus)"
    ID=ubuntu
    ID_LIKE=debian
    PRETTY_NAME="Ubuntu 16.04"
    VERSION_ID="16.04"
    HOME_URL="http://www.ubuntu.com/"
    SUPPORT_URL="http://help.ubuntu.com/"
    BUG_REPORT_URL="http://bugs.launchpad.net/ubuntu/"
    UBUNTU_CODENAME=xenial
    


    Furthermore, the following command will provide you with a neat output of your current Ubuntu version:
    $ lsb_release -da
    No LSB modules are available.
    Distributor ID:	Ubuntu
    Description:	Ubuntu Xenial Xerus (development branch)
    Release:	16.04
    Codename:	xenial
    




    Lastly, systemd command hostnamectl reveals Ubuntu version along with some other relevant information such as kernel version and more:
     $ hostnamectl
       Static hostname: linuxconfig
             Icon name: computer-desktop
               Chassis: desktop
            Machine ID: 3b348a19c578436796b717d614b868b1
               Boot ID: 1ad07ee4476a466392fc8dfa423e3b11
      Operating System: Ubuntu 16.04
                Kernel: Linux 4.4.0-18-generic
          Architecture: x86-64
