.pacnew: /etc/pam.d/sudo

On my Thinkpad-laptop, I’m using fingerprint for LogIn and sudo, t he actual file /etc/pam.d/sudo is:

auth        sufficient      pam_fprintd.so
auth        include         system-auth
account     include         system-auth
session     include         system-auth

The proposal /etc/pam.d/sudo.pacnew is:

auth		include		system-auth
account		include		system-auth
session		include		system-auth
session		optional	pam_systemd.so class=none

I’d appreciate your advice! Thank you.

Just add the last line from the .pacnew to your existing file and then delete the .pacnew.
