I confirm, both wget and curl do not work, not happy with https certificate. (current macos)

I confirm download using web browser works (current google-chrome).

But the el7 binary RPM will not work on el8 or el9.

Simplest way to proceed is to build elog from git sources, per https://elog.psi.ch/elog/download.html

mkdir -p $HOME/packages
git clone https://bitbucket.org/ritt/elog --recursive
cd elog
make
(make install is not needed, you can run elog from the git clone and build directory).

This is how we build and run elog at TRIUMF, including the MIDAS Forum elog.
