Hello Evgueni, The HWE kernel in Focal Fossa 20.04 has recently been updated from 5.8 to 5.11. Reading the logs attached, it seems your system is trying to install the new 5.11 kernel packages and is failing at this stage:
Processing triggers for linux-image-5.11.0-25-generic (5.11.0-25.27~20.04.1) ... /etc/kernel/postinst.d/initramfs-tools: update-initramfs: Generating /boot/initrd.img-5.11.0-25-generic run-parts: failed to stat component /etc/kernel/postinst.d/vboxadd: No such file or directory The file '/etc/kernel/postinst.d/vboxadd' was likely supposed to be installed by Virtualbox Guest Additions but it's either empty or not present. You mentioned that you are trying to install the newest Virtualbox Guest Additions. Was a previous version already installed before? If yes, could you try removing it and installing again? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-signed-hwe-5.11 in Ubuntu. https://bugs.launchpad.net/bugs/1939333 Title: package linux-image-5.11.0-25-generic 5.11.0-25.27~20.04.1 failed to install/upgrade: installed linux-image-5.11.0-25-generic package post- installation script subprocess returned error exit status 1 Status in linux-signed-hwe-5.11 package in Ubuntu: New Bug description: This issue appeared while VirtualBox kernel modules were being compiled for installation of the newest Guest Additions ProblemType: Package DistroRelease: Ubuntu 20.04 Package: linux-image-5.11.0-25-generic 5.11.0-25.27~20.04.1 ProcVersionSignature: Ubuntu 5.8.0-63.71~20.04.1-generic 5.8.18 Uname: Linux 5.8.0-63-generic x86_64 ApportVersion: 2.20.11-0ubuntu27.18 Architecture: amd64 CasperMD5CheckResult: skip Date: Mon Aug 9 13:57:45 2021 ErrorMessage: installed linux-image-5.11.0-25-generic package post-installation script subprocess returned error exit status 1 InstallationDate: Installed on 2021-02-13 (177 days ago) InstallationMedia: Ubuntu 20.04.2.0 LTS "Focal Fossa" - Release amd64 (20210209.1) Python3Details: /usr/bin/python3.8, Python 3.8.10, python3-minimal, 3.8.2-0ubuntu2 PythonDetails: N/A RelatedPackageVersions: dpkg 1.19.7ubuntu3 apt 2.0.6 SourcePackage: linux-signed-hwe-5.11 Title: package linux-image-5.11.0-25-generic 5.11.0-25.27~20.04.1 failed to install/upgrade: installed linux-image-5.11.0-25-generic package post-installation script subprocess returned error exit status 1 UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-signed-hwe-5.11/+bug/1939333/+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
