Answer 1

An issue like this occurred here and it was caused by wrong csv data. I changed data like [1] to [2] (adding "" on the value) in the files [3] and [4]. If it not help, check logs in system.log.

1. ""value"":%url_key=watches%

2. ""value"":""%url_key=watches%""

3. /vendor/magento/module-catalog-rule-sample-data/fixtures/catalog_rules.csv

4 ./vendor/magento/module-sales-rule-sample-data/fixtures/sales_rules.csv

Answer 2

A workaround rather than a solution:

1. Remove magento/module-grouped-product-sample-data from composer.json
2. Run composer update magento/module-grouped-product-sample-data
3. Rerun bin/magento setup:upgrade

Your sample data won't include grouped products, but the setup will complete (unless there is a similar issue with another sample data module - in such case repeat the procedure above for that module).
