/var/log/auth.log Question Relating to Ubuntu 20.04

[mahesh]

Hi,

I just entered the var/log/auth.log command in my Ubuntu 20.04 terminal.

These are some of the results I didn't understand:

- /etc/securetty no such file

[I believe this is a Ubuntu 20.04 bug of some sort but how to get rid of it?]

-unregistered Authentication Agent for unix-session: c1 disconnected from bus

-gkr - pam stashed password to try later in open session


Thanks.
