@scooke I wanted to clarify my concern about this issue. Previously, after a system reboot was completed, the "reboot" button in notification would automatically fade to grey and disable the reboot button. This functionality appears to have changed (button remains clickable and red). The color difference you mentioned wasn't actually my concern. At this point, I understand this is the new expected behavior, so I consider this matter resolved.

Previously, the notification disappeared after rebooting, but that's no longer happening. Like @SansGuidon mentioned, when I see the notification, I assume a reboot is needed - which is exactly why we implemented this notification system in the first place.

Very misleading in the current iteration.

I've also verified the non-existence of reboot-required, here was my steps:

First, check if the file exists:

ls -l /var/run/reboot-required

verify when your system was last rebooted using:

uptime

or

last reboot

After the reboot:

Check if the file still exists:

ls -l /var/run/reboot-required

check the system logs to verify the reboot actually occurred:

journalctl --boot

or

dmesg | grep -i 'Linux version'

I can also confirm that even though I have Upgraded from 22.04 to Ubuntu 24.04 (Noble Numbat) following the official Cloudron docs at https://docs.cloudron.io/guides/upgrade-ubuntu-24/?ref=blog.cloudron.io and successfully upgrading I'm still seeing the persistent reboot notification in the UI. I have even tried rebooting from both the Vultr console and through the System Info panel within the Cloudron UI to no avail

Thank you for the reply on this Joseph. I have checked that /var/run directory and I do not see that file, however, I still see the reboot required in the UI.

I have a persistent Ubuntu notification that started appearing yesterday at 9:54 PM stating "Reboot Required - To finish ubuntu security updates, a reboot is necessary."

Usually when I receive these notifications, clicking the reboot button resolves the issue. However, this time, even after clicking the reboot button, the notification remains and continues to indicate that a reboot is needed.

What steps should I take to resolve this? Thank you for your help!
