[SOLVED] unknown filesystem type 'crypto_LUKS'

Hey guys. This seems like a really stupid problem I'm having given that I have installed countless times and now for whatever reason I'm stuck on this issue

I am following the dm-crypt wiki for a full system with encrypted boot found here https://wiki.archlinux.org/index.php/Dm … .28GRUB.29
Completely following the instructions, only deviating on things like names of partitions. I create LUKS partitions and the lvm logical partitions on top afterwards, and get to the point where I'm mounting the filesystems. All are mounted A-ok until I get to /dev/sda1 which is the EFI system partition. when I try to mount it at /mnt/boot/efi (after /mnt/boot had been mounted) I get

mount: unknown filesystem type 'crypto_LUKS'

I Have no idea why I am getting this error. I'm using the latest 2017.03 iso. I have installed using this particular setup, even down to the same commands and everything before (even with this iso).

lsblk currently gives me:

NAME              	  MAJ:MIN RM   SIZE RO TYPE  MOUNTPOINT
sda                       8:0      0   200G  0 disk
├─sda1                    8:1      0   512M  0 part
├─sda2                    8:2      0   200M  0 part

└─sda3                    8:3      0 237.8G  0 part
  └─lvm                 254:0      0 237.8G  0 crypt
    ├─vg1-swap          254:1      0     8G  0 lvm   [SWAP]
    ├─vg1-root          254:2      0    20G  0 lvm   /mnt
    └─vg1-home          254:3      0 209.8G  0 lvm   /mnt/home
...

It appears that mount doesn't like mounting straight onto the luks partition, which is odd because I've done this before.

Re: [SOLVED] unknown filesystem type 'crypto_LUKS'

Why is the ESP a crypto_LUKS container not a fat32 filesystem?

ESP must be FAT32: https://wiki.archlinux.org/index.php/EF … _Partition

Re: [SOLVED] unknown filesystem type 'crypto_LUKS'

*facepalm* Thank you guys. I formatted $ESP as vfat -F32 and mounted it and it worked perfectly. Making as solved. Gonna go crawl back into my corner now.
