I installed the Gantry 5 framework no problem into Joomla! (using "Upload Package File"), then I tried to install the theme for it and I received this error:

'/opt/bitnami/apps/joomla/htdocs/templates/g5_hydrogen/custom/config/default' failed on error mkdir(): Permission denied

Clearly it is some sort of permission issue.

You have to add sudo word before your command line.

ie sudo chmod 777 <path>


Check out the user and group you are running you WebServer. Then you should change user and group owner:

chown user:group  /opt/bitnami/apps/joomla/htdocs/templates/g5_hydrogen/custom/

The user that you are trying to make the directory with either does not have permissions to make a directory in that location, or you simply need to add the word sudo before the command.

Try adding sudo first and see what the response is. Either the directory will be created as you want, or you do not have sudo permissions meaning that you need to login as someone with sudo permissions and make the directory.

However, once you have logged in as a user that does have the permissions required to make a directory there you could change the permissions of the file path so that the original user you tried could make a directory there, which can be accomplished using the chmod command.
