Comment 21 for bug 1817559

Specification updated <https://wiki.ubuntu.com/SoftwareUpdates?action=diff&rev2=230&rev1=229>: ‘Whenever “Automatically check for updates:” is set to “Never” (so any security updates are known from manual or previous checks), the “When there are security updates:” menu should consist of options “Remind me daily” (the default), “Remind me every two days”, “Remind me weekly”, and “Remind me every two weeks”. Whenever “Automatically check for updates:” is set to anything other than “Never”, the “When there are security updates:” menu should instead consist of options “Display immediately” (the default) and “Install automatically”.’
