Just updated to 20.04 final release, and I'm seeing these messages in
May 14 06:29:52 Satellite-E55 gdm-password]: pam_unix(gdm-password:auth): Couldn't open /etc/securetty: No such file or directory May 14 07:40:14 Satellite-E55 su: pam_unix(su:auth): Couldn't open /etc/securetty: No such file or directory
I looked back at a 19.10 VM, and
/etc/securetty was there. All my 20.04 systems are missing this file. Two 20.04 installations are upgrades, and one installation is a fresh install VM.
What's up with this file missing in 20.04? Should I restore a copy from 19.10?
The same problem occurs in 20.10, in both upgrades and fresh installs.
