More than one value for the key user.name Git

Question

For some reason I\'m getting the error that \"More than one value for the key user.name\" when I try to set the user.name for my git account. How can I set it to a single n

To debug such things you may use this command:

git config --list --show-origin

It shows the origin file for each configuration entry.
Example output with duplicated core.autocrlf and unwanted C:\\ProgramData/Git/config file:

$ git config --list --show-origin
file:"C:\\ProgramData/Git/config"       core.symlinks=false
file:"C:\\ProgramData/Git/config"       core.autocrlf=true
file:"C:\\ProgramData/Git/config"       core.fscache=true
file:"C:\\ProgramData/Git/config"       color.diff=auto
file:"C:\\ProgramData/Git/config"       color.status=auto
file:"C:\\ProgramData/Git/config"       color.branch=auto
file:"C:\\Program Files\\Git\\mingw64/etc/gitconfig"    diff.astextplain.textconv=astextplain
file:"C:\\Program Files\\Git\\mingw64/etc/gitconfig"    filter.lfs.clean=git-lfs clean -- %f
file:"C:\\Program Files\\Git\\mingw64/etc/gitconfig"    filter.lfs.smudge=git-lfs smudge -- %f
file:"C:\\Program Files\\Git\\mingw64/etc/gitconfig"    filter.lfs.required=true
file:"C:\\Program Files\\Git\\mingw64/etc/gitconfig"    filter.lfs.process=git-lfs filter-process
file:"C:\\Program Files\\Git\\mingw64/etc/gitconfig"    credential.helper=manager
file:C:/Users/john.doe/.gitconfig   user.name=John Doe
file:C:/Users/john.doe/.gitconfig   user.email=john.doe@somemail.com
file:C:/Users/john.doe/.gitconfig   core.preloadindex=true
file:C:/Users/john.doe/.gitconfig   core.fscache=true
file:C:/Users/john.doe/.gitconfig   core.autocrlf=input
file:C:/Users/john.doe/.gitconfig   gc.auto=256
file:.git/config        core.filemode=false
file:.git/config        core.bare=false
file:.git/config        core.logallrefupdates=true
file:.git/config        core.symlinks=false
file:.git/config        core.ignorecase=true
file:.git/config        core.autocrlf=input

You may do the same with --system and --global to check where your gitconfig files are located:

git config --global --list --show-origin

Example output:

file:C:/Users/john.doe/.gitconfig   user.name=John Doe
file:C:/Users/john.doe/.gitconfig   user.email=john.doe@somemail.com
file:C:/Users/john.doe/.gitconfig   core.preloadindex=true
file:C:/Users/john.doe/.gitconfig   core.fscache=true
file:C:/Users/john.doe/.gitconfig   core.autocrlf=input
file:C:/Users/john.doe/.gitconfig   gc.auto=256
