SSL certificate verification failure in GetPoplog.sh Ubuntu 22.04

These days wget likes you to verify the referenced domains. I verified that www.cs.bham.ac.uk doesn't have a proper SSL certificate configured. To fix this , add --no-check-certificate to script, or update the sub domain SSL certas.

wget https://www.cs.bham.ac.uk/research/projects/poplog/V16/DL/packages-V16.tar.bz2

Affects curl commands in make as well.

The ideal would be to host these files on a secure domain. The easiest recommendation is to put these on Amazon S3 as a public read only object, assuming there is no option to fix the DNS to use https.

The fallback workaround:

wget --insecure

curl -k
