Issue during deleting all cache in magento 2

December 16th, 2016 sagar Magento 2

Normally you delete all cache either using

php bin/magento cache:flush --all

1	php bin/magento cache:flush --all

Or,

rm -rf var/cache/* var/page_cache/* var/view_preprocessed/* var/generation/*

1	rm -rf var/cache/* var/page_cache/* var/view_preprocessed/* var/generation/*

You may receive some errors as
