Lab15_1 step 16 ubuntu pod, Is the package apt-transport-https installed?
in Step 16,
``kubectl run -i --tty ubuntu \
--image=ubuntu:16.04 --restart=Never -- bash -il
Looks like the repos use https and since the container do not contain apt-transport-https, it will not update.
curl or wget is not on the image so I don't see a way to even fetch the package to add it. Any advice?
Output:
root@ubuntu:/etc/apt# apt update
Reading package lists... Done
E: The method driver /usr/lib/apt/methods/https could not be found.

Hi @sylvainmartin,
In this lab the only strange thing I experience is that I can no longer (at least for now) download the helm 2.7 package. I downloaded helm 2.8 instead to be able to reproduce step 16, and with both images "ubuntu:16.04" and just plain "ubuntu" I was able to "apt (and apt-get) update/upgrade/install". I would expect we both pulled the same ubuntu:16.04 image from the repo.
Did you try re-creating the client pod? Did you see the same behavior?
Regards,

after much conntrack'ing, tcpdump'ing I found my issue... it's appending my search extra from my k8s dhcp vlan to /etc/resolv.conf and I have a *.mydomain.com dns entry that points to my treaffik frontend for my docker env

Ah, the fun of dealing with DNS
I assume in Lab 10.1 (Ingress) step 15 you did not encounter any issues while running "apt update" and "apt install".0 -
I skipped over that one, I'm going to redo all of them again, I've got my test next week. but I figured since part of the test will most likely have a "this is broken, fix it" I might has well try to figure out the problem

Nice troubleshooting!
Good luck on your test!0
