Hello.
At Sage Days 77 we felt that it would be helpful to have a mailing list

Thanks for reporting this and even providing a workaround :)
You are right, Sage was built with libssl-dev but the final container had
been missing openssl. I fixed it for the 8.2 build and pushed a new image
to the Docker Hub.

Hello.
since Sage 8.2 sage.parallel.ncpus.ncpus() returns 1 if you have no
environment variables such as MAKE, SAGE_NUM_THREADS, MAKEOPTS set.
This number is used by the @parallel decorator and similar constructions to

p-adic numbers as keys. That dict used to be a cache which is not
