Public bug reported: Hi,
I've installed Lubuntu 18.04 and found that problem: the display-manager service complains: ● lightdm.service - Light Display Manager Loaded: loaded (/lib/systemd/system/lightdm.service; indirect; vendor preset: enabled) Active: active (running) since Wed 2018-05-02 11:36:27 CEST; 1min 22s ago Docs: man:lightdm(1) Process: 1717 ExecStartPre=/bin/sh -c [ "$(basename $(cat /etc/X11/default-display-manager 2>/dev/null))" = "lightdm" ] (code=exited, status=0/SUCCESS) Main PID: 1720 (lightdm) Tasks: 6 (limit: 4915) CGroup: /system.slice/lightdm.service ├─1720 /usr/sbin/lightdm ├─1726 /usr/lib/xorg/Xorg -core :0 -seat seat0 -auth /var/run/lightdm/root/:0 -nolisten tcp vt7 -novtswitch └─1786 lightdm --session-child 12 19 Mai 02 11:36:29 pcdanisch lightdm[1735]: PAM unable to dlopen(pam_kwallet5.so): /lib/security/pam_kwallet5.so: cannot open shared object file: No such file or directory Mai 02 11:36:29 pcdanisch lightdm[1735]: PAM adding faulty module: pam_kwallet5.so Mai 02 11:36:29 pcdanisch lightdm[1735]: pam_unix(lightdm-greeter:session): session opened for user lightdm by (uid=0) Mai 02 11:36:30 pcdanisch lightdm[1786]: PAM unable to dlopen(pam_gnome_keyring.so): /lib/security/pam_gnome_keyring.so: cannot open shared object file: No such file or directory Mai 02 11:36:30 pcdanisch lightdm[1786]: PAM adding faulty module: pam_gnome_keyring.so Mai 02 11:36:30 pcdanisch lightdm[1786]: PAM unable to dlopen(pam_kwallet.so): /lib/security/pam_kwallet.so: cannot open shared object file: No such file or directory Mai 02 11:36:30 pcdanisch lightdm[1786]: PAM adding faulty module: pam_kwallet.so Mai 02 11:36:30 pcdanisch lightdm[1786]: PAM unable to dlopen(pam_kwallet5.so): /lib/security/pam_kwallet5.so: cannot open shared object file: No such file or directory Mai 02 11:36:30 pcdanisch lightdm[1786]: PAM adding faulty module: pam_kwallet5.so Mai 02 11:36:30 pcdanisch lightdm[1786]: pam_succeed_if(lightdm:auth): requirement "user ingroup nopasswdlogin" not met by user "danisch" It's because /etc/pam.d/lightdm and /etc/pam.d/lightdm-greeter try to load pam modules which are not installed since there are not dependencies to libpam-gnome-keyring libpam-kwallet4 libpam-kwallet5 If it is not intended to let things run into error message (and possible further trouble), you should either remove these lines from the config files or add dependencies to pull in that packages.
