In the above example, we switched the local site to the extension directory, and the remote site to the code directory. Now on the remote site window, inside app/code directory, create a folder named Magenest and go inside it. 

Now on your local site window, right-click on Wrapper extension and click Upload. The extension will be uploaded onto your host in a few minutes. 

Correct folder structure would be app/code/Magenest/[Extension Name]

The second method 

This method will require you to compress the extension into .zip or .tar.gz format, then execute the following command in your Command-Line/Terminal:

scp <path to your extension> <ssh server>:<path to Magenest directory>

Then log into your ssh server, go to Magenest directory and execute the following command to decompress the module:

unzip <.zip compressed extension>


tar -xzvf <.tar.gz compressed extension>

Now go to your Magento root directory, say it's named magento2, and execute the following commands:

sudo chmod -R 755 .

php bin/magento setup:upgrade

php bin/magento setup:static-content:deploy

sudo chmod -R 777 var pub
