I am trying to assign ownership of a certain file (FILE) to a user (A). I log in as root and run
chown A FILE but nothing happens. If I add the group option (
chown A:A FILE), the group is changed but the user is not.
If I try with another user (B:
chown B:A FILE) it works. Could anyone tell me why a specific user cannot own a file? I have tried in different locations but the result is always the same.
