If you have room for two kernels and you are booting from the newest one:
potentially, you can remove the older one to gain some space. If apt update
installs another kernel of the same version so you have two 4.19 - reboot
when the apt run finishes, make sure that the new kernel boots and runs
fine, then remove the older one. The trick is to check that you are booting
from the latest version - you don't want to remove a running kernel :(
