bad hash in repo

[Patrice Labracherie]

Hello

I have exactly the same problem :
104969ef03336523729ea1df2547267441a13cb040c778e971b74103e88dbc77 has incorrect hash.

I ve updated several 10.4 to 11.1 without problem near march/april.
In august, the same update failed on another 10.4

Today, here is the situation :
	10.4    to 11.2 		OK
	10.4    to 11.1		104....77 has incorrect hash
	11.1p10 to 11.2		104....77 has incorrect hash
	11.1p10 to 11.1		104....77 has incorrect hash
