When running php bin/magento setup:static-content:deploy command it shows above error, I just replace the magento 2.1.6 files to magento 2.1.0 files now theme working fine but when run deploy command it shows the error.Please help somebody..
Show me all file print.less, please.
Variable @media-common set in /lib/web/css/source/lib/_responsive.less
May be your theme override this core file and it no contains the variable? Check file in this path:
Also try to reset the cache in /var/view_preprocessed and try again.
rm -rf var/view_preprocessed && php bin/magento setup:static-content:deploy
