"PAM: Authentication failure" while installing dovecot-core, what should I do about it?
I was trying to install mail server following this guide
Webmail on your Debian server: exim4 + dovecot + roundcube
but while I was installing with
sudo apt-get install dovecot-core dovecot-imapd dovecot-mysql
this error showed up halfway.
Setting up dovecot-core (1:2.2.9-1ubuntu5) ... chfn: PAM: Authentication failure adduser: `/usr/bin/chfn -f Dovecot mail server dovecot' returned error code 1. Exiting. chfn: PAM: Authentication failure adduser: `/usr/bin/chfn -f Dovecot login user dovenull' returned error code 1. Exiting.
I tried to install with sudo apt-get install --reinstall dovecot-core , but the error didn't show up anymore.
should I do anything to fix it ?
I'm using Ubuntu 14.10 btw .
