Re: [racket] handin-server install problem: gnu-gunzip bad header

I'm sorry, I'm still not seeing how this can happen, unless the file is corrupt. I've pushed a change to DrRacket so that it prints the first 100 characters of the file it is trying to unpack in hopes that that might give us a clue to what's going wrong. There should be a new snapshot build availa

[racket] handin-server install problem: gnu-gunzip bad header

2014-04-02 Thread Breanndán Ó Nualláin
This semester I set up a handin server and all my students are using it ...except for one. When he tries to install the prepared plt file via "Install .plt file", DrRacket gives the complaint "gnu-gunzip bad header". Does anyone have a pointer to what the problem might be? He's using DrRacket v6.
