Several of the mirrors appear to be hosting a bad version of ipython-5.8.0.tar.gz that does not match the expected checksum in the Sage build tree:
$ cat build/pkgs/ipython/checksums.ini tarball=ipython-VERSION.tar.gz sha1=987b66cc662db8bd2ae96eee2f2237266d0c92dc md5=7014b8824981eef2cb893ea5398d6b8d cksum=226069384 $ wget http://www-ftp.lip6.fr/pub/math/sagemath/spkg/upstream/ipython/ipython-5.8.0.tar.gz $ sha1sum ipython-5.8.0.tar.gz 3ac43b6a6f40ef5c30cff2137e16f210ef4a6ec0 ipython-5.8.0.tar.gz $ md5sum ipython-5.8.0.tar.gz dec482b42b285aaf5430e2aabf54bff1 ipython-5.8.0.tar.gz I haven't checked any other packages but it makes me wonder.
