[j-nsp] M20 issues installing Junos 10

[Juan C. Crespo R.]

Hi Guys

     I've been trying to install the Junos 10 into one M20 with Routing 
Engine 3.0 (with one SSD of 8GB) and I getting this error

Adding jbase...

gzip: stdin: invalid compressed data--format violated
tar: Unexpected EOF in archive
tar: Error is not recoverable: exiting now

Any idea?

Thanks
