以下docker文件：
ADD http://kr.archive.ubuntu.com/ubuntu/pool/universe/a/audit/libaudit0_1.7.18-1ubuntu1_amd64.deb /
RUN dpkg -i /libaudit0_1.7.18-1ubuntu1_amd64.deb
给了我以下错误：
dpkg-deb: error: `/libaudit0_1.7.18-1ubuntu1_amd64.deb' is not a debian format archive
dpkg: error processing archive /libaudit0_1.7.18-1ubuntu1_amd64.deb (--install):
subprocess dpkg-deb --control returned error exit status 2
Errors were encountered while processing:
/libaudit0_1.7.18-1ubuntu1_amd64.deb
我该如何解决？
