One of my instances is stuck at login screen (viewed on system logs) after restarting or stop then start! Can't SSH to it!

Question

I have 4 instances on EC2 and there is only one of them that I can't connect to in SSH even if I restart or stop then start it. After long minutes of initialisation, the instance console tells me that "1/2 verifications succeed" and when I check the System Logs, I see that the instance is stuck at the login screen. It show "Ubunutu 20.4 LTS <my_instance name> login :". I really need this instance, it's very important!

PS : how can I attached pictures to my question?

Answer

For troubleshooting, you might want to see if the [EC2 Serial Console](https://aws.amazon.com/about-aws/whats-new/2021/03/introducing-ec2-serial-console/) can help.

When the instance is shut down (not terminated!) you can attach the EBS volume to a working instance to change the filesystem - but that may only help if you know what is wrong.

Finally, the AWS EC2 support team are there to help - raise a support ticket with them if you are stuck; the challenge with re:Post is that we don't have access to your environment; we can supply information and suggestions only.

Answer

What if you try the take a snapshot of the instance and then try recreating it?

Answer

Hi, you could try this [Troubleshoot instances with failed status checks](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/TroubleshootingInstances.html)

re:Post doesn't cater attachments at this stage, you could use something like https://puush.me/
