OK, I reported it at https://bugs.kde.org/show_bug.cgi?id=331665 (doesn't Launchpad have some facility to track bugs in upstream?).
At other times the Check for Updates option did appear in the More menu after muon-updater downloaded latest information, and this didn't take very long. The good news from the KDE bug report is the bug is probably fixed in muon-updater 2.2 series. ** Bug watch added: KDE Bug Tracking System #331665 https://bugs.kde.org/show_bug.cgi?id=331665 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1286422 Title: muon-updater prompts to click missing "Check for updates" button To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/muon/+bug/1286422/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
