remove old linux kernels

[wencyfutado]

How does one remove the extra entries of the old linux kernels after upgrade of a new version. Remember Synaptic used to do that but it was the case when Startup manager used to do a good job. Please help if i'm missing something.

This is how I do it might be easier ways.

open terminal and see what kernel you are using.


uname -a

then see what is installed


dpkg-query -l | awk '/linux-image-*/ {print $2}'

remove the ones that you do not want


sudo apt-get --purge remove <Kernel>

then

sudo update-grub


MAKE SURE YOU DO NOT DELETE THE KERNEL THAT YOU ARE USING
