Thank you for taking the time to report this problem and help to improve Ubuntu.
Unfortunately, the DpkgTerminalLog.txt that was attached to your bug report includes no output from the attempt to install the shim-signed package, so it is impossible to diagnose this problem. Please check /var/log/apt/term.log on your system for information about the failure to install the shim-signed package, and if information is present, please attach it to this bug report. ** 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/1822233 Title: package shim-signed 1.38+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/1822233/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
