Weird sample data installation issue

[CoreyCole]

I'm getting a weird issue trying to install sample data on a fresh webstore. I've wiped the database and pulled a fresh directory. I'm able to install without sample data, but when I run
composer require magento/sample-data:1.0.0-beta
bin/magento setup:upgrade
bin/magento sampledata:install admin

I get the following output:

~/html/magento2$ bin/magento sampledata:install admin

Have you ever been able to do it? If so did you change anything?

Also, even though there's no need you might as well clean the var/generation and var/cache directories and try again.

Yes I've been able to before, but this time I'm trying to install the 1.0.0-beta sample data.

I just tried switching my version to "version": "0.74.0-beta16" and my sample data version to "magento/sample-data": "0.74.0-beta16" in my composer.json file. It works just fine that way.

@CoreyCole Is your magento2 install actually 1.0.0-beta too? I think you might be trying to install 1.0.0-beta sample data on an older magento version.

[CoreyCole]

I did a fresh clone and in my composer.json the version line said 1.0.0-beta before I changed it.

sample-data:1.0.0-beta is compatible only with Magento 1.0.0-beta https://github.com/magento/magento2/tree/master. Version in develop branch is not stable and can produce some errors.

[CoreyCole]

Thanks! Running git checkout master made the installation run smoothly.

Same happened here with a fresh install of Magento 2 from this repo. I would say it is exatly the same scenario. @CoreyCole how did you fixed this? If I try to do a git checkout master i get
[magetwod@sip1-176 public_html]$ git checkout master
error: Your local changes to the following files would be overwritten by checkout:
composer.json
composer.lock
Please, commit your changes or stash them before you can switch branches.

+1 for this error, used a clean install and it happens.

I can confirm the solution proposed here works. After doing git checkout master and git pull I'm able to install Magento 2 with sample data.

[CoreyCole]

Try git checkout -f -b master

Thank you @CoreyCole, I was just trying the same thing. Master branch works w/sample data.
