This happen with a bad configuration of `tramp-default-proxies-alist':

--8<---------------cut here---------------start------------->8---
(add-to-list 'tramp-default-proxies-alist
             '(nil "\\`root\\'" "/ssh:%h:"))
--8<---------------cut here---------------end--------------->8---

With this with host set to nil,
(directory-file-p "/sudo:localhost:")
C-x C-f "/sudo:localhost:"
eshell/sudo
fail with error above.
The host should be set to the real name of the host we want to connect
on as root:

--8<---------------cut here---------------start------------->8---
(add-to-list 'tramp-default-proxies-alist
             '("\\`realhostname\\'" "\\`root\\'" "/ssh:%h:"))
--8<---------------cut here---------------end--------------->8---

No but you can reproduce easily with:

$ eshell/sudo fdisk -l
=>/bin/sh: fdisk: not found
