apt vs apt-get error code

When we run apt-get update and if it fails, a non zero error code should be returned, but in my case its still 0. See below:

This is intentional; see #778357:
The results are meaningful. 0 indicates success or transient error, whereas
other values indicate a persistent error.

Thanks for the answer. Transient errors? What causes it? Or how can it be fixed? Here I just removed internet access from a VM and run apt-get update. It returns non zero error code on other ubuntu VMs, but this one is returning 0.
– Vijay47
Feb 8 at 13:17
I am mostly concerned why its returning 0 in this VM only.
– Vijay47
Feb 8 at 13:21
A transient error refers to an error which will fix itself at some point, in all likelihood — basically,apt-get updatereturns non-zero only if human intervention is needed. If you’re seeing varying behaviour from one VM to another, you should mention that in your question.

By default it returns non zero, thats why it was not mentioned in the question
