Answer 1

1. remove var/cache var/view_preprocessed var/page_cache var/generation var/di
2. run php bin/magento setup:upgrade
php bin/magento setup:di:compile
php bin/magento cache:clean

Should works.
If no, run also php bin/magento setup:static-content:deploy

Answer 2

You can navigate to cache folder by cd /var/cache , Then use rm -rf *

So it should delete all the files & folder inside the cache folder, Follow the same for rest of the folders and follow the second setup which mention above.
