[Ifeffit] LARCH installation issue in UBUNTU 18

[Uma Mahendra Kumar K]

Dear All,

              I wanted to install LARCH on Ubuntu 18. And I could not.

I have tried several methods  (miniconda, Anaconda, from source and the Linux Binaries and even through pip).

 For several issues , I found answers in Ifeffit mailing list. This is new.

lmfit is not able to import 'ufloat'.

Actually "ufloat" belongs to "uncertainties". I could not able to link(port) them properly.

I need your help to install Larch.

the following is the error message

Traceback (most recent call last):
