I have a ubuntu machine and want to change the IP address, the requirements are as follow:-

  • using only cli to change the IP address, since the HW is not accessible and the script is changing the IP address through SSH, so it has to be the only cli
  • The changes to be permanent, the IP address shouldn't be lost on restart
  • This should be applicable to all the version of ubuntu

The ubuntu in question is a VM with the default static IP already configured can be accessed with the SSH.

Is there any way to change the IP address of ubuntu with the above requirement?

preferably it should be supported from version 14 - 20 (only stable build)

I'm trying to download the netboot ubuntu 18.04 image and using this link

It has directories and file directly. So trying to download all the files and sub-directory recursively... For that, I'm using following command:

wget -m http://archive.ubuntu.com/ubuntu/dists/bionic-updates/main/installer-amd64/current/images/netboot/ubuntu-installer/

which gives following error:

--2020-03-16 14:23:12--  http://archive.ubuntu.com/ubuntu/dists/bionic-updates/main/installer- 
amd64/current/images/netboot/ubuntu-installer/
Resolving archive.ubuntu.com (archive.ubuntu.com)... failed: Temporary failure in name resolution.
wget: unable to resolve host address ‘archive.ubuntu.com’


Not sure what is the reason behind this error, any help/direction is appreciated!

I want ubuntu as VM in KVM with qcow2 format.

currently I can get the .iso format want can convert to the qcow2 format but this doesn't work.

so for this there cloud image with .img format and can be converted to the qcow2 format with qemu-img command and it works but the problem is that it has cloud-init which gives errors with the on-prem deployment in KVM

so, conclusion: qcow2 from .iso not working with KVM and qcow2 with .img is working but it has cloud init.

I want server ubuntu image with .img format with cloud-init.

I want to download the ubuntu server image and install it without internet

I searched the internet for the server image and got ubuntu-18.04.4-live-server-amd64.iso which require internet to install

is there any image that does not require the internet to download?

I don't have the console so I cannot just click continue when it fails to connect to internet, as I am going to deploy this image as VM in KVM.
