Error while installing cudnn7.0.5 with deb

My system is Ubuntu 16.04.3 LTS. While I try to install cudnn 7.0.5 with deb file, the runtime file could be installed correctly, but the developer file and the doc file encounter a problem as below:

dpkg-deb (subprocess): decompressing archive member: lzma error: compressed data is corrupt
dpkg-deb: error: subprocess returned error exit status 2
dpkg: error processing archive libcudnn7-dev_7.0.5.15-1+cuda9.1_amd64.deb (–install): cannot copy extracted data for ‘./usr/lib/x86_64-linux-gnu/libcudnn_static_v7.a’ to ‘/usr/lib/x86_64-linux-gnu/libcudnn_static_v7.a.dpkg-new’: unexpected end of file or stream
Errors were encountered while processing:libcudnn7-dev_7.0.5.15-1+cuda9.1_amd64.deb

The same error occurs on installing doc file.

maybe you need to try the download again
