OMG. This is not Windows, you know. This is not Windows. Updates are
your friend. Do them early, do them often.

I update my machines _every day_.

I have command history for the root account. So, as soon as the PC has
turned on, I do:

sudo -s
[password]
[up-arrow]
apt update ; apt full-upgrade -y ; apt autoremove -y; apt purge ; apt clean

Then if anything important like the kernel was updated, I reboot.
Firefox will nag you if it needs a restart. Most other things, I
ignore and get on with it.

I do this on all my Ubuntu, Devuan/Debian and openSUSE boxes.

The openSUSE version needs more interaction but its package-management
tools are a bit clunkier, but they're in deep denial about this and
won't fix it.

You should expect to be rebooting every day, and if you have not
rebooted a machine at least 1/2 dozen times, then you have not tested
it properly and it is not ready to be deployed yet.

You didn't test it enough. :-(

What motherboard? What firmware version? Have you checked for updates?
What medium is it booting off? Is there anything difficult or tricky
in there, like LVM, partitioning, ZFS, anything like that?
