Issue/Introduction

To be able to upgrade, the /boot filesystem needs to be cleaned up to free up space to install the new kernel .

What is the command to delete the old kernels?

 

Environment

API Gateway 11.X

Resolution

To free up space in /boot filesystem, you can remove old unused kernels. The following command will show installed kernels:

dpkg --list | egrep -i --color 'linux-image|linux-headers'

ii  linux-image-5.10.0-33-amd64       5.10.226-1                         amd64        Linux 5.10 for 64-bit PCs (signed)
ii  linux-image-amd64                       5.10.226-1                         amd64        Linux for 64-bit PCs (meta-package)

If you have multiple kernel versions,  you can remove the unused one with one of the following commands:

apt-get --purge remove linux-image-5.10.0-33-amd64

sudo apt-get --purge remove linux-image-5.10.0-33-amd64
