-- 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/1851382 Title: Missing modules for cryptography and NFSv4 Status in linux package in Ubuntu: Confirmed Bug description: There are two essential kernel modules that are missing from some linux kernel packages under Ubuntu Server 18.04 LTS: nfsv4.ko and aes-x86_64.ko (matter-of-fact any crypto module) I found them both missing in linux-kvm and nfsv4.ko missing in linux- generic - both are present in linux-generic-hwe-18.04. The use cases for these are not far-fetched: In an Ubuntu KVM guest, I often need virtual disks that I can encrypt via LUKS in order to protect them (somewhat). Obviously, this is not possible without the crypto modules, which are not present in the KVM- specialised kernel package 'linux-kvm'. On the other hand, when I want to mount NFS storage, I cannot use NFSv4, which is the preferred way of doing it when you need firewalling. Why this fails is not at all obvious, since the use-level "mount.nfs4" is present, but only gives cryptic messages, not showing that a kernel module is missing. And even with the default kernel (linux-generic), which has some more modules, NFSv4 client support is missing. Do I really have to use linux-generic-hwe-18.04 for that? It seems a bit much. --- ProblemType: Bug AlsaDevices: Error: command ['ls', '-l', '/dev/snd/'] failed with exit code 2: ls: cannot access '/dev/snd/': No such file or directory AplayDevices: Error: [Errno 2] No such file or directory: 'aplay': 'aplay' ApportVersion: 2.20.9-0ubuntu7.9 Architecture: amd64 ArecordDevices: Error: [Errno 2] No such file or directory: 'arecord': 'arecord' CRDA: N/A DistroRelease: Ubuntu 18.04 HibernationDevice: RESUME=/dev/mapper/unifi--vg-swap_1 InstallationDate: Installed on 2017-02-11 (996 days ago) InstallationMedia: Ubuntu-Server 16.04.1 LTS "Xenial Xerus" - Release amd64 (20160719) IwConfig: Error: [Errno 2] No such file or directory: 'iwconfig': 'iwconfig' Lsusb: Error: command ['lsusb'] failed with exit code 1: MachineType: QEMU Standard PC (i440FX + PIIX, 1996) Package: linux (not installed) ProcFB: Error: [Errno 2] No such file or directory: '/proc/fb' ProcKernelCmdLine: BOOT_IMAGE=/vmlinuz-4.15.0-1048-kvm root=/dev/mapper/hostname--vg-root ro net.ifnames=0 biosdevname=0 ProcVersionSignature: Ubuntu 4.15.0-1048.48-kvm 4.15.18 RelatedPackageVersions: linux-restricted-modules-4.15.0-1048-kvm N/A linux-backports-modules-4.15.0-1048-kvm N/A linux-firmware 1.173.9 RfKill: Error: [Errno 2] No such file or directory: 'rfkill': 'rfkill' Tags: bionic Uname: Linux 4.15.0-1048-kvm x86_64 UnreportableReason: This report is about a package that is not installed.
