Describe your issue
When i try to fetch the list of updates, i get an error message. However, (some) updates are shown afterwards, but when i try to update my apps, more similar error messages are showing up and the system shows unexpected behaviour. For example, retrieving my Vaultwarden vault on chrome runs for an unexpected long time.
