How a build a source package taken from a previous Ubuntu release?

Question

I'm trying to build curlftpfs sources downloaded from Ubuntu 23.10 universe repository on Ubuntu 24.04 LTS but debuild fails :

$ mkdir -p src/curlftpfs
$ cd src/curlftpfs
$ wget -c http://archive.ubuntu.com/ubuntu/pool/universe/c/curlftpfs/curlftpfs_0.9.2-9build1.dsc http://archive.ubuntu.com/ubuntu/pool/universe/c/curlftpfs/curlftpfs_0.9.2.orig.tar.gz http://archive.ubuntu.com/ubuntu/pool/universe/c/curlftpfs/curlftpfs_0.9.2-9build1.debian.tar.xz
