Hi list, I ran pacman -Syu on one of my LXC containers running Arch and subsequently could not log on to it using lxc-console. The login screen would appear at first but the credentials entry was messed up. Every time I enter my credentials, I get back a login prompt, and several times the password entry would not even be obfuscated but show the typed text. At any rate, no matter how often I would try to login, it would fail. Luckily, lxc-attach still worked so I could easily check the logs, here an extract: Nov 17 15:49:51 fileserver login[90]: pam_unix(login:auth): authentication failure; logname=LOGIN uid=0 euid=0 tty=pts/0 ruser= Nov 17 15:49:54 fileserver login[90]: FAILED LOGIN 1 FROM pts/0 FOR viktor, Authentication failure Nov 17 15:49:57 fileserver login[90]: pam_securetty(login:auth): unexpected response from failed conversation function Nov 17 15:49:57 fileserver login[90]: pam_securetty(login:auth): cannot determine username Nov 17 15:49:57 fileserver login[90]: pam_nologin(login:auth): cannot determine username Nov 17 15:49:57 fileserver login[90]: FAILED LOGIN SESSION FROM pts/0 FOR (unknown), Error in service module Nov 17 15:49:57 fileserver login[86]: pam_tally(login:auth): pam_get_uid; no such user Nov 17 15:50:00 fileserver systemd[1]: container-getty@0.service: Service has no hold-off time, scheduling restart.

Nov 17 15:50:04 fileserver agetty[109]: pts/0: input overrun I solved my issue simply by commenting the line auth required pam_securetty.so in the file /etc/pam.d/login, and now I can properly log in using lxc-console. Does anyone know what the exact issue is here, and if there is a better way to handle this than I presented? Thanks, Viktor
