I had the same problem with the i386-package, but now it's instalable. But then another problem occurs. Since 2 days every aptitude safe- or dist-upgrade installs 1.8.3-5+lenny1 again and again.
Even removing gnumeric and installing again brings the same result.... # apt-cache policy gnumeric gnumeric: Installed: 1.8.3-5+lenny1 Candidate: 1.8.3-5+lenny1 Version table: 1.8.3-5+lenny1 0 900 http://ftp2.de.debian.org lenny/main Packages 1.8.3-5+lenny1 0 1000 http://security.debian.org lenny/updates/main Packages *** 1.8.3-5+lenny1 0 100 /var/lib/dpkg/status # aptitude safe-upgrade Reading package lists...
