hi
I've just started having errors building PETSc on both my Github CI
pipeline and on another machine, as a result of zlib failing to
download. (I'm using the download-zlib option.) The error is:
UNABLE to CONFIGURE with GIVEN OPTIONS (see configure.log for details):
Error during download/extract/detection of ZLIB:
Unable to download package ZLIB from: http://www.zlib.net/zlib-1.2.11.tar.gz
...
Unable to download package ZLIB from:
http://ftp.mcs.anl.gov/pub/petsc/externalpackages/zlib-1.2.11.tar.gz
...
Unable to download package ZLIB from:

...
Unable to download package ZLIB from:
https://www.mcs.anl.gov/petsc/mirror/externalpackages/zlib-1.2.11.tar.gz
When I test these URLs, the first one from www.zlib.net does indeed give
a 404. But the other ones are valid. I assumed that it's trying these
URLs in sequence until it finds one that works?
I am using an older version of PETSc (3.15.5) as there is a PETSc bug in
more recent versions that affects my project and means I can't upgrade
until it is resolved.
Regards, Adrian
