To remove the kernel that was previously upgraded, download the following procedure:

1. Command: dpkg--get-selections|grep Linux View system kernel

With image is the system kernel

2. Command: UNAME-A//view system currently using kernel

This machine is currently using the 4.2.0-36 kernel; the unused kernel can be deleted, freeing up space;

3. Command: sudo apt-get remove linux-image-4.2.0-30-generic//delete unused kernels

Repeat this operation to delete the extra kernel. Each deletion of a kernel can release more than 200 m of space;

4. Sudo update-grub//Update boot boot entry
