I sometimes use gnome-software to check for updates on Debian. My repositories are Debian Stable, Flathub and a few others each dedicated to a single program. When I do sudo apt-get update on Terminal my system is able to reach all repositories managed by it without issues and I can sudo apt-get upgrade just fine. However when I go to gnome-software, move to the Updates tab and click Refresh, I get the following error time to time:
Unable to get list of updates: Failed to update metadadta for lvfs: checksum failure: failed to verify data, expected [HASH]
Is this something to worry about?
