Since upgrading to Proxmox 6 I can no longer login to new containers I have just created (although older containers I created using Proxmox 5.4 continue to work). I am performing these steps:
  • Create CT
  • Input hostname "login-test"
  • Provide a password "faceface1" and confirm the same
  • Don't enter SSH key
  • Provide template from my NFS share. I have tried Debian 10.0.1, Ubuntu 18.04, and Ubuntu 19.04
  • Select: Network - IPv4 DHCP, IPv6 DHCP
  • Check "Start after created"
  • Everything else is completely default
When the container starts I open an xterm console and enter "root" and then "faceface1" as the password and get the error "Login incorrect". I see these entries in /var/log/auth.log:
Code:
Jul 28 04:58:17 login-test login[333]: pam_unix(login:auth): authentication failure; logname=LOGIN uid=0 euid=0 tty=/dev/tty1 ruser= rhost=  user=root
Jul 28 04:58:20 login-test login[333]: FAILED LOGIN (1) on '/dev/tty1' FOR 'root', Authentication failure

I am able to enter
Code:
pct enter 104
from a host session to enter the container (this is how I got the logging above).

I have ALSO tried to add an SSH public key during container creation, but when I attempt to SSH into the container I just get prompted for a password (the key is ignored) and the login information is incorrect. Same outcome essentially.

Is anyone else hitting this?
 
could you verify that your /etc/shadow file inside the container contains a line for the root user that's not starting with "root:*:" ?
 
WOW I just created a new container to check the answer to your question and it worked perfectly and I can login. The only change I've made to Proxmox is activating a subscription and reverting my apt sources back to stock. I haven't even rebooted. I'm not sure what to say.

FWIW on this working container my /etc/shadow file does have a line for root that does not start with root:*:
