Dear all, after upgrading to kernel 6.12.4- the Virtual Box stopped working and vboxconfig produces the following output: vboxconfig Building kernel modules... Kernel modules built correctly. They will now be installed. insmod /usr/lib/modules/6.12.4-1.g16f6531-default/updates/vboxdrv.ko modprobe: ERROR: could not insert 'vboxnetflt': Key was rejected by service insmod /usr/lib/modules/6.12.4-1.g16f6531-default/updates/vboxdrv.ko modprobe: ERROR: could not insert 'vboxnetadp': Key was rejected by service Kernel modules are installed and loaded. But the opensuse signing key is enrolled. Further information from modinfo shows vboxdrv not signed: modinfo vboxdrv filename: /usr/lib/modules/6.12.4-1.g16f6531- default/updates/vboxdrv.ko version: 7.1.4_SUSE r165100 (0x00340001) license: GPL description: Oracle VirtualBox Support Driver author: Oracle and/or its affiliates suserelease: openSUSE Tumbleweed srcversion: 1D640EFCE74255CFEC18A1C depends: name: vboxdrv retpoline: Y vermagic: 6.12.4-1.g16f6531-default SMP preempt mod_unload modversions parm: disabled:Disable automatic module loading (int) parm: force_async_tsc:force the asynchronous TSC mode (int) Is this intentional and does that mean I will have to sign the modules from now on by myself? Any help is really appreciated, thank you in advance! Br Niclaas
