Got this error with One Click install. Here’s a quick run down of what I did to resolve in the event that someone else encounters the same issue.

1) change to ghost user

sudo -i -u ghost-mgr

2) remove botched/broken install directory

sudo rm -r /var/www/ghost

3) add nodejs source (maybe unnecessary, idk)

curl -sL https://deb.nodesource.com/setup_10.x | sudo -E bash 
4) run updates

sudo apt-get update
sudo apt-get upgrade

5) update nodejs

sudo apt-get install -y nodejs

6) recreate install dir and set permissions 

sudo mkdir /var/www/ghost
sudo chown ghost-mgr:ghost-mgr /var/www/ghost

7) re-run install command. (just copy this from the terminal output of the failed install to get the command with your MYSQL pw. Will look like:

ghost install –auto –db=mysql –dbhost=localhost –dbname=ghost_production –dbuser=ghost –dbpass=veryNicePassword –dir=/var/www/ghost –start

That did the trick for me. Worth note, I first tried on a $5 droplet and then moved to a $10 droplet based on comments above. I don't think that matters though and I'm guessing the above fix would work on $5 droplet as well. 

Same problem here. Ended up installing it on my own.

has this been fix yet? , having the same issue

Still having same issue on 2019, really sucks…

Infuriating. Feel like I’m being “punked” trying to use this system. I’ve been trying for months. I RTFM and have followed directions in the docs to create a “one-click” Ghost. It’s just unusable, inexcusable. “One-click” is misused here.

Welll… bummerrrrrrrr..... it doesn’t work.... great. I was hoping to roll out a Ghost site in 1.2.3..... but nothing....

same here. tried the “click once” option and now stuck in hell.

can’t run any ghost commands because

Working directory is not a recognisable Ghost installation.
Run `ghost config` again within a folder where Ghost was installed with Ghost-CLI.

i figured out command needs to be run from /var/www/ghost but no matter what i do, i still get 502 Bad Geteway when i try to go to http://my_ip/ghost

Another reason it would not install correctly is if the ghost database user account is not using the correct password during install. I ran into that problem, where I needed to update the password of the ghost user to the same password used in the install script. After that everything else worked as expected.
