The most likely cause of this is LP: #1734147. If you are affected by this issue, it is important that you follow the steps to reset your firmware's writability, because a drive failure in the future could leave you unable to boot any operating system at all on your computer. This issue will definitely not be cleared by apt -f install. However, while it's a serious issue, there should also be no harm at all in rebooting. You won't be able to upgrade your bootloader until this issue is resolved, but the bootloader you currently have on disk should continue to work as before. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1744424 Title: package shim-signed 1.33.1+13-0ubuntu2 failed to install/upgrade: installed shim-signed package post-installation script subprocess returned error exit status 1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/shim-signed/+bug/1744424/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
