I'm trying to install Ubuntu 18.04 on my laptop. After choosing the partitionn i have the following error message: grub-efi-amd64-signed package failed to install into / target/.

enter image description here

Then I tried to install via "try ubuntu" and i get:

ubi-partman failed with exit code 10

enter image description here

What should I do?

  • what does /var/log/syslog file say near the end? – rogerdpack Jun 23 '19 at 6:31

Do the following (for beginners):

I assume you already have a flash usb with ubuntu .iso

  1. Boot your usb on try ubuntu

  2. Ubuntu Software enter image description here > install Gparted enter image description here

  3. Open gparted, right click on you desired partition to install Ubuntu > new > New Size : 200 MiB; filw system: fat32; > Add ; Something like this should be done: enter image description here

  4. Right click on EFI partition just created, Manage flags > boot

  5. Apply changes on gparted then exit gparted

  6. Install Ubuntu, when appears where to install choose something else>

  7. double click on efi partition, choose EFI

  8. Double click on desired partition to install ubuntu, choose ext4, mount point "/"

  9. Install


Do the following:

  1. Create FAT32 partition with 200Mib with "boot" flag
  2. Run installation
  3. Choose partition to install ubuntu...
  4. Choose FAT32 partition as EFI partition
  5. Choose your swap partition if you want
  6. Install
  • This isn't at all clear. I presume I have an EFI partition and a ext4 (or whatever) / partition and I install to that partition. Do I need to format the efi partition as well as /? Where do I set grub to be installed? – sjatkins Nov 26 '20 at 10:33

this error also caused by Intel VT-x/EPT settings of Vmware Fusion on MacOS, before the installation, check it off. the screenshot
