Does this mean you boot from a recovery usb and then somehow boot the system that is installed on the hard disk ?
It seems you have experience of installing a 64bit OS on a 32bit UEFI.
If you are confident that running the 'apt-get install --reinstall grub-efi' command will fix the issue then we can look at the mechanics of the problem.
The system seems to be unable to find the required files - it reports not being able to resolve the name 'archive.ubuntu.com'
To check the name resolution and connectivity, open a terminal with Ctrl Alt and T
Execute this command at the prompt.
--- Code: ---ping -c 5 archive.ubuntu.com
--- End code ---
The expected good response is that the system will convert the server name to an address and then send 5 test packets which should elicit 5 responses from the server and report this with some statistics. If ok the number of packets transmitted will equal the number of packets received. If not ok, there is something wrong, so report back with the response.
If the response is ok, the next step would be to try pasting this link into a browser.
http://archive.ubuntu.com/ubuntu/pool/main/g/grub2-unsigned/
This should show you a file list - if not let us know what happens instead.
If you can see a file list check that 'grub-efi-amd64_2.06-2ubuntu14.4_amd64.deb' is listed. If it is listed then we need to dig a bit deeper.
If you are NOT confident that running the 'apt-get install --reinstall grub-efi' command will fix your issue then we need to look at how to fix the grub rescue in another way.

When you attempt to boot normally, do you get a
--- Code: ---grub>
--- End code ---
prompt? If so, the first part of this post may be helpful, particularly the grub recovery link. Ignore the "Observations:" section of that posting as that is unrelated to the grub issue.
I'm sorry I can't help you with the apparently broken state of your apt configuration as I've never gotten into that situation.

hi i have a asus t100taf, it has a baytrail cpu.
i did a sudo apt-get dist-upgrade and it ended up messing up grub. so i can only get into the system with a recovery usb. Because if i try to boot regularly i will end up at grub resucue.
this is the code i get when i try to run sudo apt-get grub-efi:
--- Code: ---apt-get install --reinstall grub-efi
