I see this same behaviour regularly on systems running 18.04 as well. Running sudo apt update makes the update process resume - no errors shown.
Without doing that the system reports that it is up to date and it isn't, making it unsafe. Non techy users freak out on using a command line command. I think this could and should be self healing, eg by running an apt update on resume after network up. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1557215 Title: "The update information is outdated" warning won't go away.
