Starting Lab Exercise 5.2.2 you need to run the CreateNFS.sh script. I'm wondering if there is an updated script I need or at least how to change it to download the required package:

This should install some package but fails:

Should be ready. Test here and second node

    Hello @berniefitz ,

    The existing script is good, no changes needed to that. I am glad you were able to fix the issue encountered and move forward with the exercise.

    Here is why you got the error:

    1. The script runs the "apt-get update" command before installing the nfs-server package. The update process failed due to updates made to the Kubernetes repository over the weekend. The legacy package repositories - apt.kubernetes.io have been deprecated and frozen. Hence you received the error:

    "E: The repository 'https://apt.kubernetes.io kubernetes-xenial Release' no longer has a Release file.
    N: Updating from such a repository can't be done securely, and is therefore disabled by default."

    1. After the script encountered the error, it didn't execute next command of installing the nfs-server and subsequently all the other nfs commands in the script failed.

    What needs to be done now?

    Since you got it to working, No action is needed from your end. If you encounter similar error due to package repository, you need to
    1. removed the old source - i.e. edit /etc/apt/sources.list.d/apt_kubernetes_io and remove the line "deb https://apt.kubernetes.io/ kubernetes-xenial main"
    2. Add the appropriate Kubernetes apt repository : Refer to this link

    The installation scripts in the latest release of this course, i.e. 1.29.1 has all the update repositories. If you haven't downloaded the latest solutions tarball, please do so.

    Thanks,
    Fazlur

    I manually installed sudo apt install nfs-kernel-server and then commented the line out from the script. All seems to be working now
