Auto update, 1-click installer: "Failed to connect to FTP Server" SSH on Unbuntu

We were having issues getting the one-click installer to work.

We ended-up changing the owner/group of our wordpress folder, and all files/folders inside, to www-data/www-data.

So, let’s say our WP folder lives here:

/blah/wp/

Using the shell:

$ cd /blah/
$ sudo chown -R www-data:www-data wp
$ cd wp
$ sudo chown -R www-data:www-data *

In other words, not only did everything inside the WP folde need to have owner/group be www-data, the parent folder that houses the WP install needed www-data owner/group permissions.

Just wanted to post this info for others in the same predicament.
