Public bug reported: With a fresh install of Ubuntu 24.04 LTS on an older notebook with a Broadcom BCM4352 WLAN chip and secure boot enabled, I tried to get WiFi running by installing the bcmwl-kernel-source package. Unfortunately, the module does not load:
> sudo modprobe wl modprobe: ERROR: could not insert 'wl': Key was rejected by service I was then following the procedure described here, to sign the wl kernel module manually: https://askubuntu.com/questions/760671/could-not-load-vboxdrv-after- upgrade-to-ubuntu-16-04-and-i-want-to-keep-secur/ This resulted in this warning - but the module wl module did not load either. >dkms status broadcom-sta/6.30.223.271, 6.8.0-38-generic, x86_64: installed (WARNING! Diff between built and installed module!) Can you advise how to get the wl kernel module running? Thank you in advance. ------------------------------------------------------------------------------------------------- Description: Ubuntu 24.04 LTS Release: 24.04 bcmwl-kernel-source: Installed: 6.30.223.271+bdcom-23ubuntu1 Candidate: 6.30.223.271+bdcom-23ubuntu1 Version table: *** 6.30.223.271+bdcom-23ubuntu1 500 500 http://de.archive.ubuntu.com/ubuntu noble/restricted amd64 Packages 100 /var/lib/dpkg/status 02:00.0 Network controller [0280]: Broadcom Inc. and subsidiaries BCM4352 802.11ac Dual Band Wireless Network Adapter [14e4:43b1] (rev 03) Subsystem: Lenovo BCM4352 802.11ac Dual Band Wireless Network Adapter [17aa:0623] Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx- Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Latency: 0, Cache Line Size: 64 bytes Interrupt: pin A routed to IRQ 255 IOMMU group: 10 Region 0: Memory at c1200000 (64-bit, non-prefetchable) [size=32K] Region 2: Memory at c1000000 (64-bit, non-prefetchable) [size=2M] Capabilities: <access denied> Kernel modules: bcma, wl ProblemType: Bug DistroRelease: Ubuntu 24.04 Package: bcmwl-kernel-source 6.30.223.271+bdcom-23ubuntu1 ProcVersionSignature: Ubuntu 6.8.0-38.38-generic 6.8.8 Uname: Linux 6.8.0-38-generic x86_64 ApportVersion: 2.28.1-0ubuntu3 Architecture: amd64 CasperMD5CheckResult: pass CurrentDesktop: ubuntu:GNOME Date: Tue Jul 16 22:38:08 2024 InstallationDate: Installed on 2024-07-14 (2 days ago) InstallationMedia: Ubuntu 24.04 LTS "Noble Numbat" - Release amd64 (20240424) ProcEnviron: LANG=en_US.UTF-8 PATH=(custom, no user) SHELL=/bin/bash TERM=xterm-256color XDG_RUNTIME_DIR=<set> SourcePackage: broadcom-sta UpgradeStatus: No upgrade log present (probably fresh install) ** Affects: broadcom-sta (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug noble wayland-session -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2073303 Title: Broadcom WLAN kernel module not loaded when secure boot is enabled To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/broadcom-sta/+bug/2073303/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
