Created attachment 141967 [details] KDE Crash Report Discovery continuously crashes after an update. Multiple attempts, restarts and Konsole/Terminal commands have not been able to fix it. It opens stating that it is not connected to the internet, which is confirmed untrue as I can browse the internet on Firefox. Once it "connects" it, attempts to load - and then crashes. STEPS TO REPRODUCE 1. Click on Discovery 2. Wait to "connect" 3. Loads - then crashes OBSERVED RESULT Discovery crashes and is unable to load EXPECTED RESULT Discovery to open so I can check for Updates SOFTWARE/OS VERSIONS Qt Version: 5.15.3 Frameworks Version: 5.86.0 Operating System: Linux 5.11.0-36-generic x86_64 Windowing System: X11 Drkonqi Version: 5.22.5 Distribution: KDE neon User Edition 5.22 ADDITIONAL INFORMATION Please see attached (generated) kcrash file for more information
Created attachment 141968 [details] New crash information added by DrKonqi plasma-discover (5.22.5) using Qt 5.15.3 - What I was doing when the application crashed: Checking Discovery for Updates - Unusual behavior I noticed: It opened, stating that there was no internet connection - which is not true, as I had a steady and stable connection. - Custom settings of the application: None that I can remember. Automatic updates are turned on in System Settings however. -- Backtrace (Reduced): #4 0x00007fb5c5955d8c in std::__atomic_base<int>::load (__m=std::memory_order_relaxed, this=0x51) at /usr/include/c++/9/bits/atomic_base.h:413 #5 QAtomicOps<int>::loadRelaxed<int> (_q_value=...) at /usr/include/x86_64-linux-gnu/qt5/QtCore/qatomic_cxx11.h:239 #6 QBasicAtomicInteger<int>::loadRelaxed (this=0x51) at /usr/include/x86_64-linux-gnu/qt5/QtCore/qbasicatomic.h:107 #7 QtPrivate::RefCount::isShared (this=0x51) at /usr/include/x86_64-linux-gnu/qt5/QtCore/qrefcount.h:101 [...] #9 QHash<QUrl, Attica::Provider>::insert (avalue=..., akey=..., this=0x564c5309c388) at /usr/include/x86_64-linux-gnu/qt5/QtCore/qhash.h:770
This is the message in Discovery when I attempt to open it: "Unable to load applications" "Please verify Internet connectivity"
Do you have networkmanager installed but disabled, by any chance?

No. I do not have Network Manager installed - not that I would know how to confirm this. There is nothing in the Applications list or search results. Could you please confirm / explain how to install this - since I cannot access Discover
(In reply to Nate Graham from comment #3) > Do you have networkmanager installed but disabled, by any chance? No. I do not have Network Manager installed - not that I would know how to confirm this. There is nothing in the Applications list or search results. Could you please confirm / explain how to install this - since I cannot access Discover
Depends in your distro; search for something called "networkmanager". However if the Plasma Networks applet in the System Tray works for you, then you do have NetworkManager installed, since it requires that.
Is this issue still happening? The issue looks rather confusing and I don't see where it's coming from. An updated backtrace would help as well.
