Bionic: PostgresQL 10 no longer starts up

Environments Linux
1

Recently my builds started failing although the Travis config did not change. I’m trying to run Postgres v10 in Bionic. The error I get is:

Starting PostgreSQL v10
Job for postgresql@10-main.service failed because the service did not take the steps required by its unit configuration.
See "systemctl status postgresql@10-main.service" and "journalctl -xe" for details.
sudo systemctl start postgresql@10-main

I’ve created a minimal repro to demonstrate. Here is the failed job. Here are the relevant parts of the config:

dist: bionic
sudo: false
services:
  - postgresql
addons:
  postgresql: "10"
  apt:
    packages:
      - postgresql-10
      - postgresql-client-10
      - postgresql-contrib-10
before_install:
  - psql -d template1 -U postgres -c "CREATE USER pinafore WITH PASSWORD 'pinafore' CREATEDB;"

Of course it fails when it tries to run psql because it cannot connect:

psql: could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?

This code was working as of about a week ago.

Update: switching from bionic to xenial works. So this appears to just be a problem with bionic.

We are running into the same issue since today. Nothing changed on our end. Anyone else is experiencing it?

@san983 same here, have raised a ticket but no response yet.

If it’s happening recently, please point to the failing build URL.

My quick tests are working.

Can’t post links (I’m on .com not .org), but my builds continue to fail:

travis_setup_postgresql 10

@BanzaiMan I think I’ve figured out what’s causing it by looking at your config. My project’s .travis.yml file looked like this:

addons:
    postgresql: "10"
    apt:
        packages:
            - postgresql-10
            - postgresql-client-10

This was working absolutely fine as recently as yesterday. However, yours looks like this:

addons:
    postgresql: "10"

Removing the apt section from mine resolved the issue, but this is definitely a change on Travis’ end as my config has not changed since yesterday and previously passing builds now fail.

I see. My guess would be that our addon is making changes to the apt packages (which is installed earlier) and that is causing the problem.

Thanks @HappyTepid. I drove my fix, but just removing postgresql-10, I needed the postgresql-client-10 package

So, this configuration is explicitly stated in our documentation.

We will look into fixing this.

@BanzaiMan Thanks for providing a suggestion. For what is worth, I shared links and detailed examples via support on the ticket I opened on Thursday. I yet have to receive a reply after 4 days :confused:

We ultimately addressed it by removing postgresql-10 as suggested here. I’d love to better understand if my support request got lost in the wire.

Still have this issue here https://travis-ci.org/github/Suor/django-cacheops/builds/687369517. Surprisingly PostgreSQL still starts up sometimes, but usually don’t.

Me too. It appears that postgresql 9.3 is now starting up somehow. Still debugging too :frowning:

I’m experiencing the same issue. Builds that were passing until about May 14th are now failing.

I can also confirm that removing postgresql-10 and postgresql-client-10 appears to fix it:

I’m still seeing this issue today in Bionic. Unfortunately since I’m using postgresql-contrib-10, none of the solutions posted above worked for me. However, this did:
