Apt Upgrade – Will Apt Upgrade with Yes Flag Reboot if Needed?

aptupgrade

For example, if I run sudo apt-get -y upgrade if there is a package that requires a restart to upgrade, will the yes flag cause the system to reboot after the command finishes upgrading everything? Or, will it still require a manual reboot?

OS and Software:

  • Debian Buster 10 -> kernel version 4.19 on a Raspbian HW

  • apt 1.8.2 (armhf)

Best Answer

No, apt on its own won’t reboot.

You can check whether the file /var/run/reboot-required exists after running apt to see if a reboot is required. If you use unattended-upgrades, you can configure that to reboot for you.
