I have been struggling to get the updates working in Wordpress. I have a Wordpress install from rocketthemes.com and I unpacked it and it is working great. But when I go to update after following this tutorial https://www.digitalocean.com/community/tutorials/how-to-configure-secure-updates-and-installations-in-wordpress-on-ubuntu I cannot update or add new themes. I have went through all the comments and the tutorial several times and I am stumped. I used the same custom port that I set up in the beginning. I am using the LAMP set-up and have my root files at /var/www/html. If anyone can help, let me know what more info I can provide to help you assess the problem. Thanks to anyone who can help.
