I have two Ubuntu server 16.04.

I have enabled unattended upgrade for the two servers and the same configuration.

He upgrades one package the same version into the two servers but only one he shows me the message that needs a reboot.

Anyone know why only one of the server need reboot?

Unattended upgrade returned: True

Warning: A reboot is required to complete this upgrade.

Packages that were upgraded: A

Which package is it? Try to install needrestart and see if that suggests that you need to reboot the servers.

  • The package it was the tcpdump, but it was not the first time this happens on the two servers. Thank you for your answer.
