shim-signed Depends: grub2-common (>= 2.04-1ubuntu24). grub2-common in jammy Depends: grub-common (= 2.06-2ubuntu7.2). grub-common contains /usr/lib/grub/grub-multi-install.
Please show the output of 'dpkg -l grub-common' on your system. Your bug report also shows that this was originally an Ubuntu 22.04 (jammy) system and that this is what you are currently running. Yet you are installing shim-signed 1.51.3+15.7-0ubuntu1, which is a security update that was published a year ago. That's not a good sign regarding the security of the system; but it also means there should not have been any opportunity to /usr/lib/grub/grub-multi-install to have gone temporarily missing as part of an upgrade. ** Changed in: shim-signed (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2081940 Title: package shim-signed 1.51.3+15.7-0ubuntu1 failed to install/upgrade: 已安装 shim-signed 软件包 post-installation 脚本 子进程返回错误状态 127 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/shim-signed/+bug/2081940/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
