Or asked the other way around: How long do you keep your servers running without installing any software updates?

update means something like

sudo dnf update

or something ....

apt-get upgrade
apt-get update

If I have something serious, I will set up automatic upgrades. If short downtimes are ok, also with automatic reboots when the kernel updates, but if they are not, with notifications that I should go reboot them.

If it's not anything serious, whenever I remember to.
