I am not sure if this is a Boinc problem or a Linux/QT problem. I suspect the latter, but who knows? Cross-posted on BOINC forums at UC Berkeley. OS: Linux openSUSE 15.6 Kernel version: 6.4.0 QT version: 5.15.12 BOINC-manager command line: kdesu -u boinc /usr/bin/boincmgr Boinc is running as a systemd service, username boinc. That commandline has been working properly until minutes ago, after a kernel update and reboot. Now, I get the following error in the system log:
