No username assigned & invalid ID after running check50


I am new to ide50, taking CS50. After I set-up my workspace, no username was assigned. I continued to do some of the practice sessions and ran my first check50 after which it replied ‘Invalid ID’. Is there something I need to do to correct these issues?


Hi there, I have the same problem. Did anyone have any suggestions? Thanks


I had an answer from Harvard’s CS50 systems admin as follows:

“In version 57 of the IDE, the terminal prompt was deliberately shortened. In version 59, the tilde (~) was accidentally expanded to its equivalent, /home/ubuntu. That will be corrected in the next release. Neither change should prevent your successful use of the IDE.”
