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 Ubuntu Bugs, which is subscribed to 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 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-signed-hwe-5.11/+bug/1939333/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
