Accordant with the answer at Would the displacement of this question help?, would you please migrate https://superuser.com/questions/679640/automatic-wallpaper-manager to another apt website like Software Recs?
As the answer says:
this question is too old to be migrated. After 60 days of asking, a question cannot be moved to another site anymore.
Consider checking with Software Recs if such a question would be acceptable there, then simply re-ask.
