I have installed OpenStack using DevStack on my local machine using VM. Then I have created an instance which can be connected from my VM using SSH. But when I try to update the system by using sudo apt update command, the instance cannot connect to internet and shows the following error.

Err:1 http://security.ubuntu.com/ubuntu focal-security InRelease
  Temporary failure resolving 'security.ubuntu.com'
Err:2 http://archive.ubuntu.com/ubuntu focal InRelease

This is my local.conf file contents.

Kindly mention do I need to add something else to configuration file or configure VM's network differently?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
