Can't upgrade libtool, libedit, or install openssh

Hi there, 

I need to install openSSH to connect to my Synology NAS for rsync backup. 

However, one dependency of openssh, libedit, refuses to upgrade. Here is the log:

:info:configure configure: creating ./config.status

Any idea why it's failing?

Thanks to all,
