Just got this message trying to update the repo:

Code:
pc@pc-System-Product-Name:/media/pc/Disco3/mame[git]/mame$ git pull
*** Please tell me who you are.

Run

  git config --global user.email "you@example.com"
  git config --global user.name "Your Name"

to set your account's default identity.
Omit --global to set the identity only in this repository.

fatal: unable to auto-detect email address (got 'pc@pc-System-Product-Name.(none)')
