how to rollback to an older kernel on 16.04/purge kernel automatically installs new one?
1
unattended-upgrade recently automatically upgrade my kernel to 4.4.0-143 but it does not work with nvidia graphic cards so i decided to roll back to previous version.
i am able to boot to an older kernel(4.4.0-141), and confirmed i'm booting my computer with that:
4.4.0-141-generic
but when i tried to apt purge linux-image-4.4.0-143-generic, apt prompts me to confirm:
The following NEW packages will be installed:
linux-image-unsigned-4.4.0-143-generic
So why is uninstalling a signed kernel requires to install an unsigned version?
And how can i safely remove the newer(143) kernel? Thanks in advance!
