After following all steps in doc: Install Discourse on Ubuntu or Debian for Development I tried running server using “bin/ember-cli -u” and (“bin/ember-cli” + “rails s” in saparate terminal windows). I am getting error as: “network error” in chat window. [Screenshot from 2025-02-26 13-53-01] Do i need to running any additional command in terminal? or did i missed something?

@merefield @j.jaffeux Thanks for the help!! The root cause of this issue related to Ubuntu 20.04 ( system’s glibc (GNU C Library)). Now this sounds strange but its true. Explanation: On investigation, I found that mini_racer-0.18.0.pre1 native extensions require glibc version 2.32+. Checking on my local machine by running: ldd --version shows glibc version: 2.31. At the end, II upgraded to Ubuntu 22.04 as it ships with glibc version 2.35 and all set :rocket:

What is the backtrace and error for the 500? My suspicion is you may not have run migrations, have you?

yes I was going to say the same but it’s definitely in the steps of the doc :man_shrugging: I would recommend you to try using: Developing Discourse using a Dev Container That should be a much easier way for you to get a working dev env.

[image] Joffrey Jaffeux: but it’s definitely in the steps of the doc :man_shrugging: Actually, is it? It may exclude plugin migrations?

@Neeraj_Keriya try: LOAD_PLUGINS=1 rake db:migrate

I ran all the command from the doc and wanted to install discourse manually (not with docker) and all three DB’s are migrated successfully. checking: LOAD_PLUGINS=1 rake db:migrate

Initially, When running “bundle install”. i got issues with gem (“mini_racer”, “0.18.pre1”) so i downgrade it to ‘~> 0.6.2’. Is that can be the cause? This is the only thing i did different from document.

Maybe, once you’ve run migrations again, check for 500 and report the detail of that error from within /logs here.

Sure, will do. BTW this is what i am getting on “rails db:create” with “mini_racer”, “0.18.pre1” bin/rails aborted!

FYI current Ruby is something closer to 3.3.6 in Production, so switching to that version of Ruby might be a good idea. (this is why @j.jaffeux recommends the docker install as these things can be a pain in non-docker dev)
