On all my existing Linux machines WinSCP works well as I'm sudoer without password.
On a new one managed by someone else, the user I have is sudoer but require to enter the password, so it's no compatible with WinSCP.
My contact tried to change rights on folders/files by adding my user to the group who is owner of the folders/files, same error (operation not permitted).
Does someone have an idea about the issue and how to fix it?
My contact can't let me be sudoer without password...
