apt-cyg install return md5sum error












5















Since the last time I reinstall windows, and then cygwin, apt-cyg stops working. It keeps telling me



"md5sum: standard input: no properly formatted MD5 checksum lines found".


What could cause the issue? And if I want to learn more about the error, where should I go and look?




Edit:
When I start to debug the problem, I realized that the md5 code generated was too long(128 char) for an md5 code(normally 32 char). Since I am using a 64-bit version of cygwin, it could be the source of the issue. But how to resolve it?

          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.




          Edit:



          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

          • The newer apt-cyg file has slightly different line numbers, but +1 for pointing me to roughly the right part of the file, and the appropriate fix. For me it was 343 and 346, and I also changed the comment too because OCD.

          Execute this from your shell:



          perl -i.bak -pe 's{md5sum}{sha512sum}g'  /usr/local/bin/apt-cyg


          Then retry.

              this version was the only one I found. Initially I thought it is old but actually its bigger than the one presented in other answers if you take in consideration line numbers.

            • OK, good to know it still exists... Somehow the lack of package manager about Cygwin really doesn't sit well with me...

            • Wasn't it taken down by DMCA's takedown notice already? The version you downloaded was probably quite old.

                    Probability when a professor distributes a quiz and homework assignment to a class of n students.

                    Image
                    0 0 $begingroup$ Need help with this problem. Suppose our lazy professor collects a quiz and a homework assignment from a class of n students one day, then distributes both the quizzes and the homework assignments back to the class in a random fashion for grading. Each student receives one quiz and one homework assignment to grade. (a) What is the probability that every student receives someone else's quiz to grade, and someone else's homework to grade? (b) What is the probability that no student receives both their own quiz and their own homework assignment to grade? In this case, some students may receive their own quiz, and others may receive their own homework assignment. (c) Compute the limiting probability as n approaches infinity in each case. ...
