PAM unable to dlopen(/usr/lib/security/pam_unix.so): /usr/lib/libresol

Not sure if this is the right forum but I'll try...

After the upgrade of glibc today, xscreensaver is not working anymore (the unlocking of desktop part). I get the follwing in the log when I try to unlock:

PAM unable to dlopen(/usr/lib/security/pam_unix.so): /usr/lib/libresolv.so.2: symbol __h_errno, version GLIBC_PRIVATE not defined in file libc.so.6 with link time reference
PAM adding faulty module: /usr/lib/security/pam_unix.so

Any way to fix this?

Regards,

BTJ

I too see this on 4 Archlinux installs, im guessing its a bug. I dont use xscreensaver, as far as i can tell everything is working as it should.

This is typical of software which uses dlopen to reference libraries provided by glibc (you'll see it with cron every time it wakes up). It's not really a bug, it's just a version mismatch. The "solution" is invariably to restart the complaining program.

The glibc updates remain pretty problematic; I've had to execute `systemctl daemon-reexec` on various machines as well to fix this
