I just installed Ubuntu 18.04 after deleting Ubuntu 17.10, I created a back up on my usb drive but Ubuntu 18.04 won't restore the files as it says "RESTORE FAILED Failed to execute child process “duplicity” (No such file or directory)"
I do not have any other copies of my ancient files and those are very important to me, can you help get my files restored, please?
Thank you very much.
