Yes, piclone is the package name for SD Card Copier. (for other viewers who need clarification)
Could you attach a screenshot of your problem?:
it starts, but cannot select any disk!
Ever wanted to run an .img file before flashing it to an SD card?
Or wished you could run Stretch on a Pi 4?
Or wanted to run two versions of Raspbian on a single Pi simultaneously?
You can do all of that, and more, with my Vdesktop script - https://bit.ly/2GeNuIw
