sudo apt-get clean
sudo apt-get update 
sudo apt-get upgrade --fix-missing

Output of update is : 

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

  Temporary failure resolving 'fr.archive.ubuntu.com'
Err:4 http://fr.archive.ubuntu.com/ubuntu xenial-backports InRelease
  Temporary failure resolving 'fr.archive.ubuntu.com'

  • What output did you get from `sudo apt-get update` as no output shows a problem as you have no sources available. (FYI: You've tagged `lubuntu` which is EOL for 16.04 LTS, only Ubuntu server (no desktop), Ubuntu desktop (Unity 7), Kylin or Ubuntu Core 16 are still supported, all flavors are EOL. The output from `sudo apt-get update` is where I'd look first for clues though. – guiverc Dec 03 '19 at 10:29

    Please don't provide additional information in comments, edit your question and add extra detail there. Greater formatting is allowed in questions/answers, it's easier to read etc.... – guiverc Dec 03 '19 at 10:33

    You have a temporary network issue, which on a VM usually means problems with the host setup in my experience (it's disabled, wrongly configured, etc). It could also be you're behind firewalls, proxy .... but I'd check your host first. – guiverc Dec 03 '19 at 10:35

It seems is just a stupid mistake I have done, I'have forgot to add DNS server name in my interfaces configurations, so all my packages can't resolves a domaine names.

Solution was :adding the line 

dns-nameservers 8.8.8.8

on the file /etc/network/interfaces
