no method named wrapping_offset_from found for raw pointer *mut i8errors

I get errors like the following when running on Ubuntu 18.04 on the master branch. Does any ideas what the cause could be?
error[E0599]: no method named `wrapping_offset_from` found for raw pointer `*mut i8` in the current scope --> util_linux/mdev.rs:582:17 | 582 | s.wrapping_offset_from(val) as libc::c_long as libc::c_int, | ^^^^^^^^^^^^^^^^^^^^ help: there is an associated function with a similar name: `wrapping_offset` | = note: try using `<*const T>::as_ref()` to get a reference to the type behind the pointer: https://doc.rust-lang.org/std/primitive.pointer.html#method.as_ref = note: using `<*const T>::as_ref()` on a pointer which is unaligned or points to invalid or uninitialized memory is undefined behavior

Think I was stuck on an old version of the Rust libs, sorry
