To solve this problem, follow the steps below (I suppose you are using Ubuntu):

1) sudo chmod -R 777 /var/www/html/magentoInstallationFolder/

2) Install Magento Extension

3) Restore correct permissions for directories and files respectively

sudo find /var/www/html/magentoInstallationFolder/ -type d -exec chmod 775 {} \;
sudo find /var/www/html/magentoInstallationFolder/ -type f -exec chmod 664 {} \;

Read more about why 777 permissions are bad and you need to restore good permission code (775) after you install the extension: https://askubuntu.com/a/30635
