Hello, Ok it does not give those initial errors that I mentioned while running the first kpartx command. That happened due to specifying wrong file name as the disk image. So, the command runs correctly, but it still does not create any loop-back-device files in /dev/mapper/.
And the second approach still doesnt work. Either it says, cannot initiate connection to the archive, or failed to connect to it, cannot resolve the connection to it. Thanks, Aastha.
