I'm a little behind on CS50x Fall 2016 right now, but I don't foresee having any issue catching up.

I'm currently trying to use check50 in CS50 IDE for pset1, and I'm using the ID 2015.fall.pset1.hello like the table of contents for pset1 tells me to.

So I'm typing check50 2015.fall.pset1.hello hello.c into ~/workspace/pset1. I get a response of: Uploading. E_UNKNOWN error.

I have tried all of these:

  • ~/workspace/pset1/ $ check50 2015.fall.pset1.hello hello.c Uploading. E_UNKNOWN error. ~/workspace/pset1/ $ check50 2016/fall/pset1/hello hello.c Checking. invalid ID ~/workspace/pset1/ $ check50 2016/x/pset1/hello hello.c Uploading. E_UNKNOWN error. ~/workspace/pset1/ $ check50 2016.fall.pset1.hello hello.c Checking. invalid ID

But none of them seem to work.

Any suggestions on how I can get check50 to work?

Thank you, John P

  • Sometimes, check50 will throw the unknown error for no apparent reason. In that case, it just needs to be retried. As for invalid ID, since you've been gone, is your class ID still valid? Can you access your cs50x gradebook? The correct format is check50 2015.fall.pset1.hello hello1.c I just tested and it worked fine. If retrying doesn't resolve your issues, you should probably contact staff for assistance. – Cliff B Oct 17 '16 at 0:31
