My Ubuntu server needs a reboot and I checked which package is asking for restart. Later, I found that libssl package needs a system reboot.

But, I don't want to restart/reboot my machine now. Is there a possible way to find out when my OS will get restarted automatically?

Generally, for how many days will it go without automatic restart/reboot of the OS?

  • Ok. Will packages force the OS to restart?

  • As said above, I've never seen it happen, but theoretically, it is not impossible. Hope it's clear now. Commented Jan 13, 2017 at 11:50

Having done some research I believe that Ubuntu will not restart automatically unless a chronjob is created telling it to Here is how to create such a chronjob otherwise I would just do a manual restart. If you don't reboot a server, it can go on for many many months.


Just a guess. Go to the machine and take the network connection down and up. See if the libssl package still needs a system reboot?

  • Yes, it needs a reboot as there are some dependent packages on it.
