The latest "Software" GUI tool told me that I have to reboot in order to install updates. I pressed "restart and update", It rebooted, installed the updates and rebooted again.

Normally, with update-manager and apt the update is happening while the system is operational, and a reboot (mostly) for kernel updates is required at the end of the process, and at the user convenience time. In other word, it was optimized to not waste the user's valuable time.

This is new to me, and something I've experience with MacOS and Windows before but I never saw anything like it with the majority of the linux distros I've used.

Is this the expected new behavior? Should I not use that "Software" tool and stick to update-manager or apt? This is confusing and somewhat unexpected.

Here is what I've experienced using pictures: Screenshot: Software Updates Clicked "Restart & Update" and saw this:

After a reboot (BIOS visible) and after some usual kernel messages this process took about 5 minutes to complete, while the system was unusable.

Once it was done, it rebooted again (BIOS visible again) and landed on GRUB:

After a booting, I saw the following notification:

And in the "Software" GUI (after noticeable wait period) I got:

Which seems buggy because of dups, but that's for another post.

  • Reboots are necessary for kernel updates. Did the kernel update?

  • @Nmath, I am well aware that reboot is necessary for kernel updates. That is not my question. What I observed is a reboot in order to install updates. Please read the details.

  • What do your apt logs tell you?
