I’m having an issue with logging in as admin user. I made a clean Vagrant install according to this guide. Now when I try to log in I’m getting 500 Internal Server Error.

It turns out it wasn’t a problem with Vagrant. I was running into the same error in development as well. Fixed in https://github.com/discourse/discourse/commit/0e656ff213d11b0d416927763c284fa98f91aa5b though I’m not sure why this wasn’t causing problems previously.

Can you try running rake db:migrate? The system user is missing on your installation for some reason.

This is what I get after running rake db:migrate: vagrant@discourse:/vagrant$ rake db:migrateake db:migrate == Seed from /vagrant/db/fixtures/001_categories.rb Removing superflous categories columns! rake aborted!

Hmm it looks like running it in Vagrant is causing some sort of error. I personally don’t use Vagrant myself so I’ll let someone who does chip in.

I believe the vagrant guide is meant for development purposes so I wouldn’t recommend running it in production.

I’m not going to use it on production. I’m trying to install in on my local dev server. The reason is what I want to make some changes to default template. For example I want best authors (most liked) to be shown on front page. Right now I have no idea how to do this. I think it would be easier to understand how template works on dev environment. But that’s another story…

Ic. I got confused when mention the Docker based install which I took as you’re trying to get your production Discourse up and running. I’m personally don’t use Vagrant in development so you’ll have to wait for someone else that does.

Oh, thank you for your support! That works for me as well :+1:

By the way I tried to make clean Docker based install on DO – everything is working like a charm there.
