I keep getting a notification that an update is available, but for some reason I can't find where this update is. I checked all the apps in the app center and none indicate an update is available. Just before this happened I unintentionally uninstalled the app center, I reinstalled it and that is when I got the notification. Then restarted the pc and it gave me the notification again. I tried sudo apt update/upgrade and found a package for amd 64 which might have something to do with my cpu, but I don't think that is something that this OS (JUNO) would notify me of.
