Description of problem: ksgrd_network_helper aborted 6/6 times when starting plasma-systemmonitor in Plasma 5.23.2 on Wayland in a Fedora 35 KDE Plasma installation. The crashes happened right after plasma-systemmonitor started to the Overview screen. 5/6 of the ksgrd_network_helper crashes had traces which involved ConnectionMapping::~ConnectionMapping as follows Core was generated by `/usr/libexec/ksysguard/ksgrd_network_helper'.

Boot a Fedora 35 KDE Plasma installation updated to 2021-11-04 with the updates-testing repo enabled 2. Log in to Plasma on Wayland 3. start konsole 4. Update from Plasma 5.22.5 to 5.23.2. I did this by the following since the full Plasma 5.23.2 at https://bodhi.fedoraproject.org/updates/FEDORA-2021-f7d19c8901 isn't in the updates-testing repo yet. 5. bodhi updates download --updateid FEDORA-2021-f7d19c8901 6. Log out of Plasma 7. Switch to another VT 8. Log in on the VT 9. Switch to the directory the Plasma 5.23.2 rpms were downloaded to 10. sudo dnf upgrade *rpm 11. reboot 12. Log into Plasma 5.23.2 on wayland 13. Start plasma-systemmonitor 5.23.2 When Plasma 5.23.2 is in the updates-testing repo the update could just be done with sudo dnf offline-upgrade download (with updates-testing enabled) sudo dnf offline-upgrade reboot Actual results: ksgrd_network_helper aborted when starting plasma-systemmonitor 5.23.2 Expected results: No crashes would happen Additional info: I didn't see anything look unusual in the plasma-systemmonitor window. These crashes didn't happen with plasma-systemmonitor 5.22.5 or earlier. I reported this problem at https://bugs.kde.org/show_bug.cgi?id=444921
Arjen Hiemstra wrote "https://invent.kde.org/plasma/libksysguard/-/merge_requests/193 takes care of the abort. That said, the abort shouldn't really happen in the first place and only seems to happen because of a packaging bug. `ksgrd_network_helper` needs `CAP_NET_RAW` to run, as it needs to capture all the packets going over network devices. It seems Fedora's package doesn't set that. That should be reported to Fedora somewhere." at https://bugs.kde.org/show_bug.cgi?id=444921#c1 The patch was backported to the libksysguard 5.23 branch as described at https://bugs.kde.org/show_bug.cgi?id=444921#c3
This message is a reminder that Fedora Linux 35 is nearing its end of life. Fedora will stop maintaining and issuing updates for Fedora Linux 35 on 2022-12-13. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a 'version' of '35'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, change the 'version' to a later Fedora Linux version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora Linux 35 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora Linux, you are encouraged to change the 'version' to a later version prior to this bug being closed.
This problem was fixed in libksysguard 5.23.3 as described at https://bugs.kde.org/show_bug.cgi?id=444921
