Ok, seems that you move the media directory or the update was not finished and the ./media directory was created but not filled and now is not possible to move it.
First, check if the /media directory in the /httpdocs/dedalo/media/ has media files. You can see the size of the directory:
cd ./httpdocs/dedalo/media
du -sh media
1.- If the media is empty, you can delete it.
2.- if the media is NOT empty, some files was moved, some files not, so, you need to recreate the media directory manually, moving the files that are not copied.
OPTION
If you have a previous copy of all. replace the dedalo_code and try to update the process with this previous copy.
Best
