    DEBIAN/UBUNTU:
    $ sudo apt install gddrescue 
    
    CENTOS/FEDORA:
    $ sudo dnf install ddrescue
    
  4. Locate your USB stick block device name:
    $ sudo fdisk -l
    Disk /dev/sdX: 7.22 GiB, 7747397632 bytes, 15131636 sectors
    Disk model: DataTraveler 2.0
    Units: sectors of 1 * 512 = 512 bytes
    Sector size (logical/physical): 512 bytes / 512 bytes
    I/O size (minimum/optimal): 512 bytes / 512 bytes
    Disklabel type: dos
    Disk identifier: 0x00000000
    
  5. Use ddrescue to create the bootable Ubuntu 22.04 USB startup disk. For example if your usb block device name is called /dev/sdX and the downloaded Ubuntu 22.04 ISO image is named jammy-desktop-amd64.iso then the command to create bootable Ubuntu 22.04 USB startup disk will be:
    $ sudo ddrescue jammy-desktop-amd64.iso /dev/sdX --force -D
    

Once the bootable Ubuntu 22.04 USB startup disk creation process is completed, remove your disk. All done.
