+I tried I again with different usb sticks and filesystems, and it seems to be happening only with VFAT (e.g not ext)
+Retracing my steps here  is what I do:
+
+1. Create a repository on my local machine
+
+2. Create a non bare repository on usb, and combine the two
+
+3. Add a file on my machine
+
+4. It doesn't synchronise, and I get the missing index error
+
+
+It happens the other way around too, if I
+
+1. Create a regular repository on usb
+
+2. Try to create a paired repository on my machine, I get a straight up
+
+       Internal Server Error
