AppCenter shows notifications for update, but none are available

Question

I keep getting notifications from AppCenter saying there is 1 update available, but when I go into AppCenter there aren't actually any updates I can get. If I close AppCenter, I just get a notification again a few minutes later saying there is an update available.

I've tried sudo apt update, sudo apt upgrade, & sudo apt dist-upgrade from the terminal and none have made it stop or go away.

At one point there actually was an update available, so AppCenter notification said there were 2 updates available. After updating, it went back to saying 1 update available again.

Please help, this is getting very annoying.

Answer 1

flatpak update 

fixed it for me as well

Answer 2

Close AppCenter, open a terminal and try:

sudo apt --fix-broken install

Let it work and now run

sudo apt update && sudo apt upgrade

After this, sometimes you need to reboot for Appcenter to stop notifying (haven't tried log off/logon though)

Answer 3

I had the same problem, but just went away by itself, check my thread.

AppCenter is showing non-existing updates badge counter

Answer 4

I just run

$ flatpak update 

without su permission

and the annoying red dot is no more.

Answer 5

I tried command line with no luck then I ran Gnome software updater and it found openh264 from flathub to update, so I assume Med Fadil's solution is another way of doing this.

Answer 6

Tried > flatpak update and this is what I got:
