I have 156 Raspberry Pi's I use for testing and I am trying to create a mirror locally so that I am not tying the network constantly with traffic for updating pi security. I am using your script to create this mirror but I keep getting errors that are outside the line count, for example, "./create_rasbian_mirror.sh: line 139: debmirror: command not found" I think I need more help in getting this working.

debmirror: command not found

Have you tried to install it? apt install debmirror

debmirror bug

--rsync-extra=none is needed to completely disable rsync(or debmirror will connect to rsync port which is not supported by server)
