I had linux mint, I reinstalled it on ubuntu, and wiped the file system.

You need to resume the folder with the old linux mint, did the testdisc analysis, but it only finds my system and the files that were deleted on ubuntu, which is now worth it ...

The old system does not find.

Have a chance to recover?

    Have a chance to recover?

    short: no

    Long: With a certain amount of luck and knowledge of the unique text passages stored in these files, you can probably (after a full byte scan) find the places on the disk where these text passages are found.

    but these “finds”, with great probability, will absolutely not help even to restore files (only fragments of these files). and about directories in general, in my opinion, there can be no talk.
