I just start with my pset6 in VirtualBoxVM. However, I cannot access the staff’s implementation of server.

sudo wget -O ~cs50/pset6/server http://cdn.cs50.net/2015/fall/psets/6/pset6/server
sudo chmod a+x ~cs50/pset6/server

Then execute the below to run the staff’s implementation of server.


And I got an Permission denied. How can I do?

enter image description here


try executing this:

sudo chown -R jharvard:students ~cs50/pset6

and try again!

  • I tried this, but now I get the following error when running the command: -bash: /home/cs50/pset6/server: cannot execute binary file: Exec format error

  • @ Joe Chittenden-Veal looks like the file is corrupted. did you try executing update50?
