Here is a small tip for IT pros to determine if a Debian/Ubuntu/Mint based Linux system requires a reboot due to lib or kernel upgrades, check these two files to keep your system safe and patched from bugs by loading a new kernel when needed:
```
cat /var/run/reboot-required
cat /var/run/reboot-required.pkgs
```
You can easily automate this with Ansible or scripts for a fleet of servers. See https://www.cyberciti.biz/faq/how-to-find-out-if-my-ubuntudebian-linux-server-needs-a-reboot/ for more info.
