@Leojangh Apologies for the delay in response and all the inconvenience caused because of the issue.

Changing a users uid affects its ability to ssh and is not recommended as a best practice. Do not edit /etc/passwd file by hand or using a text editor such as vi. This explains how to change or rename username in Linux using the usermod command.

As per mentioned in the article you might need to change the entry in password files and then remove their home folded of the user and need to change password of the user. Now since the key pair is stored under the user profile you will need to do the key pair copy again since you wont be able to use the old ssh key pair.

You can use ssh-copy-id command for same. Once done you should be able to SSH to your VM.

Hope it helps!!!
