[Spot] Spot Debian package not working due to expired certificate error for the LRDE website

Hi, I am trying to install Spot using the Debian package at www.lrde.epita.fr/repo/debian/ but it looks as though the security certificate for www.lrde.epita.fr has expired. In fact, it looks like it expired yesterday (Dec. 29th). The reason I'm installing Spot is that it's a dependency of another project I would like to install, and that project's Dockerfile uses the Debian package. It is possible to compile Spot from the source, but it is more efficient to use a Debian package (and potentially eases reproducibility, which is nice when using Docker). Would it be possible for someone to update the certificate? Thanks! - David
