How do you install Racket? What OS are you using? Can you install other Racket packages (say, raco pkg install threading)?

drasken commented

Sorry, probably missed too much of the context.

And apparently the problem is on my machine. Tryed the raco pkg install threading but still the same error in output.

Anyway, I installed racket on Ubuntu 22.04 with the sudo apt -y install racket command, now I just need to figure out what the problem is.

According to racket/racket#4306 (comment), apt-get install libssl-dev should fix the problem.

Subsequent comments indicate that this issue can also be fixed by upgrading to Racket 8.6 (the current latest version is 8.8, and we are releasing 8.9 soon). Assuming that you are currently using an old version of Racket, upgrading would be another possibility. The Racket PPA (https://launchpad.net/~plt/+archive/ubuntu/racket) seems to be defunct, but it does provide Racket 8.6, so you can also use that.

Thank you very much, I solved it.

As you pointed out (I guiltily didn't notice), the version supported installed on Ubuntu with apt is really outdated, after looking on how to update I've that the snap instead is updated to the current version 8.8, so I just Installed with sudo snap install racket , than installed sicp and now it works just fine.

Didn't try apt-get install libssl-dev , I took the chance to use a newer version.
