The SLES15 (all Service Packs) table include the quarterly update (QU) kernel versions and month they were released. The SLES8 table only shows the Service Pack kernel versions. Ii linux-image-4.15.0-50-generic 4.15.0-50.54įor RedHat or RPM based systems (CentOS, Fedora, etc.) you can query the rpm database using the rpm command. This SUSE Knowledge Base Article lists SLES9, SLES10, SLES11, SLES12 and SLE15 kernel updates/versions and their release dates. Now that you know which kernel version you are currently running, you can check the installed versions and see if there are any later releases.įor Debian based systems (Ubuntu, Mint, etc.) you can use dpkg, then use grep to filter the results and only show the kernel (linux-image). uname -rĤ.15.0-50-generic List All Installed Kernel Versions This will output the kernel version (release) number.

The /proc/version file specifies the version of the Linux kernel, the version of gcc used to compile the kernel, and the time of kernel compilation. srcversion then gets generated for all modules, including those without MODULEVERSION set: modinfo srcversion: How do I generate this from my source The srcversion file is only present when if one of the above holds. How to Check Linux Version We can log in for a remote user using the following command: ssh userserver-name Enter any one of the below commands for finding. This will give you version numbers and you can see if there is an installed version higher than the running version. To enable it, either: set MODULEVERSION for the module. Q: Is there a way I can check to see a Linux system has a newer kernel installed? For example, if a system has installed a new kernel, but has not yet rebooted to load it?Ī: Yes, you can check the currently running kernel as well as which kernels are installed.
