What changes to do in `/etc/pam.d/sudo` after getting a new pacnew file?

I have the following in /etc/pam.d/sudo:

#%PAM-1.0

auth required pam_env.so
auth sufficient pam_fprintd.so
auth sufficient pam_unix.so try_first_pass likeauth nullok
auth required pam_deny.so
auth		include		system-auth
account		include		system-auth
session		include		system-auth

And I have the following in /etc/pam.d/sudo.pacnew:

#%PAM-1.0
auth		include		system-auth
account		include		system-auth
session		include		system-auth
session		optional	pam_systemd.so class=none

What changes should I make to the non-pacnew file before removing the pacnew file?

Just add the last line of the .pacnew to your existing file.

O.k, thank you very much!

If you don’t have a fingerprint reader, you could even just copy the .pacnew over the existing one. I only have the contents of the .pacnew in mine, which is why I didn’t get a .pacnew.

Thank you very much, I don’t have a fingerprint reader so I will do that.
