I have an issue where the apt-get update command is not working correctly.



Eg below is part of the output of the command sudo apt-get update



Err:1 http://security.ubuntu.com/ubuntu xenial-security InRelease Could not resolve 'cusxwtc-mwg6'
Err:3 http://pkg.jenkins.io/debian-stable binary/ InRelease Could not resolve 'cusxwtc-mwg4'


I have tried the command host -v cy.archive.ubuntu.com and it verifies the domain name is resolved.



I have also noticed that in each failed repository retrieval i can see the Could not resolve 'cusxwtc-mwg4' which doesn't make any sense. I have tried searching for it but i get no results.



The same message is shown (Could not resolve 'cusxwtc-mwg4') if i also try to install anything using apt-get.



What does the cusxwtc-mwg4 or cusxwtc-mwg6 mean and how can this issue be resolved?



I am using a static address IP config during the above issue but the issue is fixed if i use a dhcp configuration. But uaing static address is a requirement for me.
