[slurm-users] Building Debian packages - problem

I am trying to build Slurm version 24.11.6 on an Ubuntu 22.04 system. I download and unpack the source mk-build-deps -i debian/control (not run as root) debuild -b -uc -us

I get this error repeated many times: dpkg-shlibdeps: warning: can't extract name and version from library name 'libslurmfull.so'

Has anyone seen similar issues? For information, there is an existing SLurm installation on this syste, with version 21 dpkgs from the Ubuntu repository.
