I also experienced this (Ubuntu 18.04, x64, with EFI enabled on an HP Laptop). During install, I do not have an internet connection enabled. Both checkboxes were disabled: - "Download updates..." - "Install third-party software..." Questions: a) Is the package "grub-efi-amd64-signed" simply not included in the Live CD? [WOULD SOMEONE PLEASE CHECK AND POST THE ANSWER IN THIS BUG REPORT?] If this is the case: Would executing the following in a live session before launching Ubiquity solve the problem?... $ apt install grub-efi-amd64-signed" before launching Ubiquity solve the problem? Should the Live CD come shipped with this package? Should the ubiquity package be updated to include grub-efi-amd64-signed as a "depends" or "recommends"? ...or... b) Does the Ubiquity installer need a newer updated version of this package? [WOULD SOMEONE PLEASE CHECK WHICH VERSION IS INSTALLED AND POST IN THIS BUG REPORT?] If this is the case: Would executing the following in a live session before launching Ubiquity solve the problem?... $ apt update $ apt install grub-efi-amd64-signed" before launching Ubiquity solve the problem? Perhaps Canonical needs to issue a point release Live CD (version 18.04.1?) with an updated version of this package? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1767259 Title: ubuntu 18.04 The 'grub-efi-amd64-signed' package failed to install into / targer.
