Answer 1

I faced this issue while running Linux virtual box on Windows. Sample-data csv files had CRLF endings, so they were incorrectly processed. I installed sample data via Git. Following commands helped me:

cd <path_to_sample_data>

git config core.autocrlf false

git reset --hard HEAD

Alternatevily you can run

cd <path_to_magento2>/vendor/magento

find ./ -type f -exec dos2unix {} \;
