Hello Trisquel users so I attempted to install Trisquel 9 on my computers how ever they all use the EFI firmware and during install I get the error message grub-efi-amd64-signed package failed to install here is a link to what the error looks like https://learningpenguin.net/2018/07/13/fix-grub-efi-amd64-signed-package-failed-to-install-into-target/#:~:text=The%20'grub%2Defi%2Damd64,settings%20to%20solve%20this%20problem. I have tried Trisquel, Trisquel Mini, Triskel isos and they all produce the same error. I have tried exiting rebooting wiping all partitions and starting the install again only to have the same error message.

Hello, have you created EFI partition at the installation time?

I have tried manually creating partitions both efi and / and using the guided partition tool and erase disk install methods.

Make sure that the partition table is GPT and you have created an ESP (EFI system partition).

It is also possible that Trisquel still uses Ubuntu's "ubiquity" installer, which is quite old (since ~2006) and may be buggy on (U)EFI systems. The new "subiquity" installer comes in 21.10 and will be available in Trisquel 11, if Trisquel is still Ubuntu-based by then.

There is a workaround. If your computer's UEFI firmware still supports CSM (compatibility support module), you can enable it so it works like legacy BIOS. (You'll need a BIOS Boot partition if you use CSM mode and GPT partition table.) CSM is no longer supported in recent computers (since ~2016).

Hello everyone!
Me and my friends are experiencing the same problem with EFI install. We have tried all of the options/solutions found on this website, on Internet etc., but the installer keeps returning errors. We have been trying to chroot into system form the live image, from Arch Linux, from Debian GNU/Linux to manually (re)install grub and efibootmgr -- no result. :-( It looks like the Trisquel's installer is just broken.
I also tried to install it on virtual machine (I had an idea to simply copy everything inside its EFI partition and then move it to the real HDD), but still everything crashes. I can't see the way to get this thing working neither on real hardware with EFI, nor on virtual machine. :-( It's a shame.

It is true that (U)EFI is poorly supported by Ubuntu's aged ubiquity installer. I have been complaining about its poor UEFI support for many years (since ~2013). If you need more information, I could try to see whether Ubuntu 21.10 daily builds have switched to the new installer. However, it won't be available in Trisquel until Trisquel 11.

For example, when I used Ubuntu's ubiquity installer on certain UEFI-based bare metals (set up in UEFI mode), the ESP was still blank after a "successful" installation. However, the UEFI support is very hard to improve, because the ubiquity installer was designed for (now legacy) BIOS. Canonical began to realize the obsolescence problem of the installer only since recent years, when CSM was no longer available on new systems.

Thanks for all the info guys so I was able to get Trisquel 9 installed by booting legacy mode instead of uefi mode and formatting my drive as mbr not gpt and I just manually created all of my partitions.

I hope in the future Trisquel supports efi better since I wasn't able to get installed via uefi mode.

At least I have a working system now.

I was getting the same error during the installation.By booting in legacy mode as William5565 mentioned the installation was successful.Thank you!
