The newer OS requires an APFS file system on the main drive of the computer if SSD but does not make it mandatory for an external. What I would suggest is getting an external SSD and installing Mohave through the MBP onto the new external. You can avoid having to make the external APFS. Once installed, boot to the external and use the Mac to move info/data from the MBP to the external as if you were moving to a new computer. After that is done, test everything and if OK, erase the MBP and clone the external to the MBP.
I know it sounds like a lot of work but it is a relatively "easy" way to avoid having to make your MBP have an APFS system. It's not that having APFS is bad but you could have problems with compatibility with other drives, etc. I don't know the extent of your computer hardware and what programs or files you need to access. Keeping the MBP non APFS should keep things compatible though according the some, may not be as efficient as the new file system.
In any case, I would invest in two externals and clone your present system to one before you do anything so you do have a backup should anything go wrong. If all works out, then clone the new setup to the extra drive. My advice is "you never have too many backups." :D
Suggest you look up articles on APFS vs MacOS extended to get an idea of the possible problems.

Obliged to bring back the macbook to the seller of all my mbp...(a very smart guy ..) don't boot anymore...! :verysad:

If he didn't replace any physical parts, he probably did one or more of the following resets:

I recently did a SMC reset on my sister's MBP and solved a recurring flash problem. Worth trying if you encounter any future issues.

Krissel, I have similar problems trying to back up my wife's mac mini. I thought Super Duper was cloning files every week. Every time she would get a message that copying did not work because of the APFS problem. She ignored that for a year! I realize now her mac hasn't been backed up for that long! I did post the topic here months ago, but did not understand how to fix this. You did offer advice, but I gave it up. Thank you!
I will review the problem again, and try to follow your suggestions herein to see if this works. Hope I can come back to you for advice if need be? Much thanks!

Of course, though I don't visit TS every day so be patient if you have a question. :)
Looking back at your original post in April it appears you already have your drive in APFS from the image you posted. If that is so, all you need do is get an external SSD and make it APFS for backup (use Disk Utility to do that, not Superduper).
ADSR seemed to have a somewhat different situation wherein he did not want to go the APFS route if he could avoid it. Generally speaking APFS should only be used on SSD drives and not disk drives as it would be slower than HFS+.
