How To Check All Available Kernel Version In Linux

By default, all installed Linux Kernels and their associated files are stored under /boot directory named vmlinuz.

To check all available Kernel version in Linux, run one of the following commands:

find /boot/vmli*
dpkg --list | grep linux-image
sudo dpkg ––list | egrep –i ––color ‘linux-image|linux-headers’
sudo dpkg ––list | egrep –i ––color ‘linux-image|linux-headers’ | wc –l

If you want to list all installed kernels on Ubuntu except current one, run the command:

dpkg -l 'linux-*' | sed '/^ii/!d;/'"$(uname -r | sed "s/\(.*\)-\([^0-9]\+\)/\1/")"'/d;s/^[^ ]* [^ ]* \([^ ]*\).*/\1/;/[0-9]/!d'

If you want to print the name of the kernel currently being used and the date of installation and update, run the uname command with -sv options.
