I have to install another Ubuntu OS version maybe 18.04 or any other long-term release. not able to work properly with the current version 19.10.

The problem is I have created some VMs which are very important and they are properly configured to carry out a project, so I don't want to lose those VMs plus the data on the host machine. What would be the better way to install another ubuntu LTS version in this case?

The main problem is wifi on the machine is not working and I'm not able to install any package, update or upgrade to debug the issue or follow the steps posted on help forums with the current version. The link to wireless info script output as suggested here: https://paste.ubuntu.com/p/k39gHmqXpR/

Reinstall the driver. Since you have an iwlwifi device,

sudo modprobe -r iwlwifi
sudo modprobe iwlwifi

If you just want to upgrade to LTS 20.04.1,

  1. Download the new ISO file from https://ubuntu.com/download/desktop.
  2. Copy the ISO to your home directory via a USB drive.
  3. Make a directory to mount the ISO. sudo mkdir /mnt/cdrom
  4. Mount the ISO. sudo mount -t iso9660 -o loop ~/ubuntu-20.04.1-desktop-amd64.iso /mnt/cdrom (Use the actual name of the iso.)
  5. Edit /etc/apt/sources.list and add deb file:///mnt kali main contrib non-free and comment out all other sources.
  6. update the system. sudo apt-get update and sudo apt-get dist-upgrade
  7. Unmount the iso.
