This is not a bug with Ubuntu or kernel. It is a problem with an external kernel module:
ERROR (dkms apport): binary package for rtl8821CU: 5.4.1 not found Error! Bad return status for module build on kernel: 6.8.0-60-generic (x86_64) Consult /var/lib/dkms/rtl8821CU/5.4.1/build/make.log for more information. Looking at your hardware, you do not have a Realtek RTL8821CU wireless adapter, so I'm not sure why you installed this (unless you have an external wireless adapter you use instead of the Intel one built into the laptop). You can remove the problematic module by running: sudo dkms remove rtl8821CU/5.4.1 --all ** Changed in: linux (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/2111192 Title: package linux-headers-6.8.0-60-generic 6.8.0-60.63 Status in linux package in Ubuntu: Invalid Bug description: package linux-headers-6.8.0-60-generic 6.8.0-60.63 failed to install/upgrade: il sottoprocesso installato pacchetto linux- headers-6.8.0-60-generic script post-installation ha restituito lo stato di errore 11 ProblemType: Package DistroRelease: Ubuntu 24.04 Package: linux-headers-6.8.0-60-generic 6.8.0-60.63 ProcVersionSignature: Ubuntu 6.8.0-44.44-generic 6.8.12 Uname: Linux 6.8.0-44-generic x86_64 NonfreeKernelModules: lkp_Ubuntu_6_8_0_44_44_generic_111 ApportVersion: 2.28.1-0ubuntu3.5 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/seq: santorom 3376 F.... pipewire /dev/snd/controlC1: santorom 3381 F.... wireplumber /dev/snd/controlC0: santorom 3381 F.... wireplumber /dev/snd/controlC2: santorom 3381 F.... wireplumber CRDA: N/A CasperMD5CheckResult: pass Date: Sun May 18 09:38:28 2025 ErrorMessage: il sottoprocesso installato pacchetto linux-headers-6.8.0-60-generic script post-installation ha restituito lo stato di errore 11 InstallationDate: Installed on 2023-03-01 (809 days ago) InstallationMedia: Ubuntu 22.04.1 LTS "Jammy Jellyfish" - Release amd64 (20220809.1) MachineType: LENOVO 20BHS0621X ProcFB: 0 i915drmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-6.8.0-44-generic root=UUID=e6b35454-309b-4489-af39-a20a80131bb2 ro quiet splash vt.handoff=7 Python3Details: /usr/bin/python3.12, Python 3.12.3, python3-minimal, 3.12.3-0ubuntu2 PythonDetails: N/A RelatedPackageVersions: grub-pc 2.12-1ubuntu7.1 SourcePackage: linux Title: package linux-headers-6.8.0-60-generic 6.8.0-60.63 failed to install/upgrade: il sottoprocesso installato pacchetto linux-headers-6.8.0-60-generic script post-installation ha restituito lo stato di errore 11 UpgradeStatus: Upgraded to noble on 2024-09-10 (249 days ago) dmi.bios.date: 06/02/2021 dmi.bios.release: 2.42 dmi.bios.vendor: LENOVO dmi.bios.version: GNET94WW (2.42 ) dmi.board.asset.tag: Not Available dmi.board.name: 20BHS0621X dmi.board.vendor: LENOVO dmi.board.version: 0B98401 WIN dmi.chassis.asset.tag: IT-L-7003570 dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: Not Available dmi.ec.firmware.release: 1.15 dmi.modalias: dmi:bvnLENOVO:bvrGNET94WW(2.42):bd06/02/2021:br2.42:efr1.15:svnLENOVO:pn20BHS0621X:pvrThinkPadW540:rvnLENOVO:rn20BHS0621X:rvr0B98401WIN:cvnLENOVO:ct10:cvrNotAvailable:skuLENOVO_MT_20BH: dmi.product.family: ThinkPad W540 dmi.product.name: 20BHS0621X dmi.product.sku: LENOVO_MT_20BH dmi.product.version: ThinkPad W540 dmi.sys.vendor: LENOVO To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2111192/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
