apt-cyg package management cli for cygwin

最近在windows cygwin terminal下用apt-cyg安装总出现如下错误

“MD5 sum did not match, exiting”

开始怀疑源被污染，后来查到是验证算法换了，直接修改/usr/bin/apt-cyg中329行附近的代码即可。

  wget -nc $mirror/$dn/$bn
  #digactual=$(md5sum $bn | awk NF=1)
  digactual=$(sha512sum $bn | awk NF=1)
  if [ $digest != $digactual ]
