Autobuild of octave3.0 on s390 failed due to an uninstallable libglpk0: The following packages have unmet dependencies: libglpk-dev: Depends: libglpk0 (= 4.37-1) but it is not going to be installed E: Broken packages Thsi was due to the removal of libltdl3 from unstable. Version 4.37-2 of libglpk0, which depends on liltdl7 is now installed on s390. I think the following is appropriate: gb octave3.0_1:3.0.4~rc7-1 . s390 Thanks, -- Rafael
