I prepared a patch and build a test package. Please run: zypper ar https://download.opensuse.org/repositories/home:/Vogtinator:/boo1160995/openSUSE_Leap_15.1_Update boo1160995 zypper -v dup --from boo1160995 zypper rr boo1160995 And test whether the problem still occurs. The package isn't published yet, might take a few minutes for the URL to be valid. > Sorry, I don't know about the seccomp sandbox. Can I modify/configure it? Nope, you can't even disable it...
