appcenter has updates but doesn't update

[vfjr-1968]

appcenter shows i have 190 updates available. it asks to reboot the system. i do so and the updates remain.

i have the same problem.

This happens to me also. It's because the updates are failing. Try:

sudo flatpak --system repair
flatpak --user repair
sudo apt update
sudo apt upgrade

I encountered this on a freshly installed system in a VM where the only suspect attribute was that it turned out to be memory constrained- as soon as I increased it from 2048 to 4096 MB it stopped hanging on the updates.

But it still failed to complete until after I ran the sudo flatpak --system repair command above.

Thanks for posting the solution.
