Error while trying to install Discourse

Installation
1

Hello, I have been trying to install discourse on my development server but it isn’t working and I have increased the Ram to 4gb. Can anyone please help me with it?

The error is attached…

Memory is not your problem, DNS is. The install failed because your server could not locate the rubygems server to download modules.

  • Does this error appear every time you run the installer?
  • What does the command host api.rubygems.org return?
  • What DNS is your server using?

Yes it does,

api.rubygems.org is an alias for rubygems.org.
rubygems.org has address 151.101.66.2
rubygems.org has address 151.101.194.2
rubygems.org has address 151.101.2.2
rubygems.org has address 151.101.130.2
rubygems.org mail is handled by 10 mxa.mailgun.org.
rubygems.org mail is handled by 10 mxb.mailgun.org.

You missed a question.

The host command gives reasonable output; You probably ran that outside the container. Are the same DNS servers configured inside?

5

I am connecting to the server using IP address… I just mapped the subdomain to the ip address. But on the domain example.com (which has discourse too btw uses DO nameserver).
But i want to install it on another server that has just IP address but mapped to forum.example.com.

6

Run cd /var/www/discourse && gem update bundler. What does that output?

7

The directory you typed is /var/www/discourse and when I typed this, I got bash: cd: /var/www/discourse: No such file or directory.

When I ran cd /var/discourse &amp;&amp; gem update bundler I got this :arrow_down:

The program 'gem' is currently not installed. You can install it by typing: apt install ruby

8

Sorry, I should’ve been more clear. That was meant to be run inside the container.

Does docker ps show any running containers? Does docker images show the local_discourse/app image or just discourse/base?

If the answer to both is no, then removing /var/discourse and starting over might be easier then troubleshooting why.

This is a different DO droplet to the working one, right? Is this droplet in the same DO regions as the working one? Do they have the same contents in /etc/resolv.conf?
