To workaround the issue by rebuilding and signing the driver manually: 1: Run "sudo dpkg-reconfigure bcmwl-kernel-source" to rebuild the driver. 2: Run "sudo kmodsign sha512 /var/lib/shim-signed/mok/MOK.priv /var/lib/shim-signed/mok/MOK.der /lib/modules/5.19.0-21-generic/updated/dkms/wl.ko" to sign the driver. 3: Run "sudo modprobe wl" to load the driver. At this point the WiFi module should start working and you should be able to connect to WiFi.
Note that this assumes that the wl.ko module is at /lib/modules/5.19.0-21-generic/updated/dkms/wl.ko, however since the user probably hasn't managed to update their kernel yet, it's a safe bet that this is in fact where the module is. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to dkms in Ubuntu. https://bugs.launchpad.net/bugs/1991725 Title: fails to sign kernel modules Status in dkms package in Ubuntu: Confirmed Bug description: Expected on kinetic: dkms will sign built modules with MOK key if requested.
