The error in your log is: sh: printf: I/O error
It is unclear to me how this error occurred. It appears that you were attempting an upgrade from xenial to bionic, but not using the release upgrader, and that stdout/stdin have somehow been disconnected from any tty, resulting in read/write failures for the maintainer scripts. I am not sure this is a bug that can be fixed in shim-signed. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1893495 Title: package shim-signed 1.37~18.04.6+15+1533136590.3beb971-0ubuntu1 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/1893495/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
