So, I got a notification for an update, I updated, the update manager (Add/Remove Software) tells me “Your system is up-to-date”, but the update manager still shows a red warning shield in the system tray, which upon hovering says ‘1 update available’. I was not told to reboot the system, and I didn’t.
Is this a bug?
That’s the problem: it doesn’t say. Only “1 available update”. And when I click the red shield, it says “Your system is up-to-date”. So, I have no idea what update it is referring to.
