Hello mighty community... Is this a permission issue or else? I have being struggling for 3 days..

Hi mighty community, 

I have being struggling on this for 3 days and have no luck. Any thoughts from anyone?

When I switch the layout of a theme, i got the following. And I was told it is a permission issue given "Can not open"

• error: Can not open /var/www/html/Magento2/app/design/frontend/MageBig/martfury/layout01/web/css/source/_mbdesign.less file

And I have set the following permission, and I still have the same issue...

• find . -type f -exec chmod 664 {} \;
• find . -type d -exec chmod 775 {} \;
• find ./var -type d -exec chmod 777 {} \;
• find ./pub/media -type d -exec chmod 777 {} \;
• find ./pub/static -type d -exec chmod 777 {} \;
• chmod 777 ./app/etc
• chmod 644 ./app/etc/*.xml

Another weird observation I noticed:

• After I tried to switch the theme and get the error above,
• if I delete everything in my /var/www/html/Magento2 folder
• and reinstall everything after installation,
• the default theme will be the one I choose before the deletion
• e.g. if I try to switch from 1 to 5 and failed (message aboeve), after delete & reinstall everything, the default theme will be 5 this time

Thank you!

Hi @luklau88 

There might be some permission issue.
https://devdocs.magento.com/guides/v2.3/config-guide/prod/prod_file-sys-perms.html

Try the following command once:

find . -type d -exec chmod 755 {} \; && find . -type f -exec chmod 644 {} \; && chmod u+x bin/magento

You can use sudo as well.

If still face issue, then try following commands once n sequence to re generations.

chmod -R 0777 var/ pub/ generated/
rm -rf var/cache/* var/view_preprocessed/* generated/* pub/static/*
php bin/magento setup:upgrade
php bin/magento setup:di:compile
php bin/magento setup:static-content:deploy -f
php bin/magento cache:flush

I hope it will help you!
