apt-cyg install return md5sum error
Since version 2.867, cygwin has move to sha512 checksum, however, the current version of apt-cyg is still using
md5sum rather than
sha512sum for integrity verification. That's what causes the problem.
To resolve the issue change the
md5sum in line 323 and 326 of the file "apt-cyg" with
sha512sum. It should work.
This issue has already been addressed by pull request #37: https://github.com/transcode-open/apt-cyg/pull/38. But the change has not been implemented to the master branch yet.
If you edit the file with windows program, the line breaker might be changed and causing issues such as
/usr/bin/apt-cyg: line 25: $'\r': command not found
Because bash recognized the line changer as a command. I suggest using linux editor like vim, emacs or gedit for the changing. Or you may directly use the
apt-cyg file uploaded in pull request #37: https://github.com/jfritz/apt-cyg/blob/97848cfa9ae05297c0b01daeb8ad08a70bc3b77b/apt-cyg
