"apt-get install testdisk "

Dont work

Hi, Working here okay.
First of all your apt may be locked looking for updates. There where several hundred updates pushed last night.
Second of all needs to be "sudo apt-get install testdisk" after you done with updates.

I do not know, in the past did you install a ubuntu application that did not belong in your system ?

No, but I have tried to install TestDisk from the website.

Where you not able to correct this problem ? Or did the problem reappear ?
What version of Deepin do you have now ? 15.1 or 15.1.1 ?

This years Deepin does not support any PPA's and does not support ubuntu repositories. Your Deepin is not working right because your unable to install a simple application from the Deepin repository or update your system with security updates or Deepin Patches.
If you want to experience Deepin properly, I would save your data and erase and reformat your hard drive with a clean fresh install of Deepin 15.1.1 and apply all Deepin patches and security updates.
Then only install applications from the Deepin Store or from the Deepin repository.
