Hello, I attempted this lab but only made it to section 4 before having to quit due to time. I came back today to try to pick up where I left off and I’m getting the following error with Terraform Plan:

│ Error: Error acquiring the state lock
│
│ Error message: resource temporarily unavailable
│ Lock Info:
│ ID: 88871473-06e3-4f23-539f-42ccc5276991

│
│ Terraform acquires a state lock to protect the state from being written
│ by multiple users at the same time. Please resolve the issue above and try
│ again. For most commands, you can disable locking with the “-lock=false”
│ flag, but this is not recommended.

Update, I figured it out but will leave up as reference to others. The terraform was still running.

In terminal:

See if any terraform process is still running:
ps -ef | grep -i terraform | grep -v grep

I got this response:

coder 590 337 0 12:36 pts/2 00:00:02 terraform plan

you will use the coder ID in next step (PID = 590 in my case):

Kill the stuck process (replace [PID] with the real PID from first message):

kill -9 [PID]

Then rerun terraform process
