Hi, libunwind seems to be holding off many packages to be uploaded to unstable now. https://release.debian.org/transitions/html/auto-libunwind.html But problem seems to be just ia64 and 87 days old. http://packages.qa.debian.org/libu/libunwind.html I do not understand what is holding off so long and when I expect to have the end of such blockage. Osamu
