Looks like we missed a server (most were fixed over the last 16 hours). Thanks for reporting this; hopefully the engineer will available over the next 12 hours to deal with this one as well.

The issue should be fixed for Day 17. Day 11 will likely be soon, but not yet.
Day 17: In the PostgreSQL lab (Task ID: 680772a2399a2462b6ccc666c), the PostgreSQL service is failing to start in the environment. The instructions mention that PostgreSQL should already be installed and running and also specify not to restart the service. Since the service is failing before I can run any commands, I’m unable to complete the task.
Could you please check and fix the lab setup?
Day 11 should now be fixed as well. Please try it out.
Hi Team, Can you please resolve this issue. I’m also facing same issue as postgresql service is failed and not able to complete the task because of it.
