Below are the configurations on one of the servers..

There is nothing difference with apt-get and apt commands.

Title:
  apt-get update doesn't get new packages

Status in apt package in Ubuntu:
  Incomplete

Bug description:
  apt-get update and upgrade do not upgrade the system
   
  --Steps to Reproduce---
   apt-get update and apt-get upgrade.  It shows nothing to upgrade. But the kernel level is in an old version. 
   
  New kernel packages are not shown in apt-cache. Somehow, the new packages are not being got from repo server when do apt-get update.

  Executed on 16.04.3

  Btw, not all the Ubuntu servers have that issues. I crossed check the
  sources.list among the servers, there is no difference. So don't know
  what caused some of them cannot get any update from ubuntu repo.
  However, I can install individual packages via apt-get install
  command.

  There is not any error during the apt-get update && apt-get upgrade.
  It showed nothing to upgrade.

  The servers were able to manually upgrade for a long time. But all the
  sudden, they are not upgradable. It looks it can not retrieve new
  kernel level packages during the apt-get update. The highest kernel
  level can be installed is 4.4.0-97.. not more higher..


  HWS: I mirrored this problem description, to be able to get support
  for getting this fixed. Even it seems to be an environment problem.
  But direct Q&A will probably help....
