OpenModelica/OpenModelica#17768 (for OpenModelica/OpenModelica#17767) stopped building UMFPACK, because UMFPACK in SuiteSparse 7 is GPL-2.0+ and no longer LGPL. debian/libomcsimulation.install still lists libumfpack*, so the nightly Linux builds abort in dh_install:

dh_install: warning: libomcsimulation missing files: debian/tmp/usr/lib/*/omc/libumfpack*
dh_install: error: missing files, aborting

This removes the line. The other SuiteSparse libraries (AMD, BTF, KLU, SuiteSparse_config) are still built and packaged. KLU stays the default sparse linear solver.

Only master. maintenance/v1.27 still builds UMFPACK and keeps the line.

OpenModelica/OpenModelica#17768 stopped building UMFPACK, because
UMFPACK in SuiteSparse 7 is GPL-2.0+. The libumfpack* line in
libomcsimulation.install now matches nothing, so dh_install aborts
the nightly Linux builds with "missing files".
