While using useradd command to add my user, I got this error: UX: /usr/sbin/useradd: ERROR: Inconsistent password files. See pwconv(1M). Logged in as root, I checked the no. of lines in /etc/passwd and /etc/shadow: # cat /etc/shadow |wc -l 299 # cat /etc/passwd |wc -l 300 vi /etc/passwd I saw that last line was a blank and removed the blank line. Using useradd command worked now without issues.
