Fix: This account is currently not available. (Linux SSH)

When you try to do an SSH on a particular Linux or Unix-Like Server and you get an error "This account is currently not available" that's because the user has been disabled.

$ ssh -p 22 dev@192.168.10.112
dev@192.168.10.112 password:

Last login: Wed Aug 2 11:23:51 2023 from dev@192.168.10.112

This account is currently not available.

Connection to dev closed.

Reason for the Error:

The message indicates that the user is locked. If you are the root user, you can check it using the command,

$ passwd -S dev

dev L 08/04/2023 0 99999 7 -1

As you can see the L next to dev user indicates that the user is locked.

How to fix it:

As a root user run the below command to enable the user again,

$ sudo passwd -u dev

passwd: password expiry information changed.
