[SOLVED] glibc 2.27-2 and pam 1.3.0-2 may require manual intervention

I am unsure if I am affected by the current manual update note "glibc 2.27-2 and pam 1.3.0-2 may require manual intervention".

Here are my set up and my questions...

Of course, filesystem is installed:

[user@host ~]$ pacman -Qi filesystem
[sudo] password for user:

libnss_nis is not installed but can be located:

[user@host ~]$ pacman -Qi libnss_nis
error: package 'libnss_nis' was not found
[user@host ~]$ locate libnss_nis
/usr/lib/libnss_nis-2.26.so
/usr/lib/libnss_nis.so
/usr/lib/libnss_nis.so.2
/usr/lib/libnss_nisplus-2.26.so
/usr/lib/libnss_nisplus.so
/usr/lib/libnss_nisplus.so.2

Question 1

Is there anything to do for me? And if yes, what is it? It's compeletly unclear to me right now. Am I not seeing the forest for the trees?

pam 1.3.0-1 is installed, pam 1.3.0-2 is not:

[user@host ~]$ pacman -Qi pam 1.3.0-2
Name            : pam
Version         : 1.3.0-1

I do not see any shared objects in /etc/pam.d/:

[user@host ~]$ cd /etc/pam.d/ && ls -R |grep "\.so$"
[user@host pam.d]$

[user@host pam.d]$ locate pam_unix_*.so
[user@host pam.d]$ locate pam_unix.so
/usr/lib/security/pam_unix.so

I also do not see any configuration files in /etc/pam.d/. Pambase is installed:

[user@host pam.d]$ pacman -Qi pambase

Question 2

Again, I am unsure if there is anything to do for me. The message seem ambiguous to me.

It has already been a very long week with not enough sleep. Yet, I need to install another package to finish a project before the weekend starts.
Help and directions are appreciated.

For question 1 have you manually modified /etc/nsswitch.conf
For question 2

There should not be any shared objects under /etc you want to search the contents of the configuration files

grep pam_unix_.* /etc/pam.d/*

Every file in /etc/pam.d should be a configuration file. Have you changed any of them?

jared · 2018-04-26 22:19:15

loqs, thank you for taking the time...

Question 1:
I have not manually modified /etc/nsswitch.conf

Question 2:
I have not changed any of the configuration files in /etc/pam.d.

loqs · 2018-04-26 23:05:01

As the default /etc/nsswitch.conf supplied does not use compat or NIS or NIS+ you can see man nsswitch.conf for more information no intervention is required for point 1.
If you have not modified any files under /etc/pam.d then it unlikely that any of those configuration files reference pam_unix2 or pam_unix_*.so

grep -e pam_unix2 -e pam_unix_. /etc/pam.d/*

I think the above should verify that then no intervention is required for point 2.

I took some time yesterday to make sure I did not forget anything. The update was finde.
Thank you @loqs for your help!
