Solved : Cisco [Authentication failed due to problem verifying server certificate? ] Ubuntu

Hello Guys are you facing issue to connect VPN in Ubuntu OS recently?

Are you facing Authentication failed due to problem verifying server certificate?  

Recently I was facing this issue in my Ubuntu OS. 

Solution: As suggested by one of my friend who loved opensource product much. 

Here is some ca-certificate related update released from Ubuntu recently. So I update the 

ca-certificate using below command and its working fine for me.

$sudo apt update

$sudo apt dist-upgrade

And now its working fine for me. Hope this is useful to you people also.
