Hi all,
I have errors:

root@unl01:~# apt update
Hit http://security.ubuntu.com trusty-security InRelease
Ign http://us.archive.ubuntu.com trusty InRelease
E: The method driver /usr/lib/apt/methods/https could not be found.
N: Is the package apt-transport-https installed?
root@unl01:~# ^C

can you tell me what is the reason?

or you have proxy on internet or firewall
or simply no internet with dns properly configured
