As one can see on http://packages.ubuntu.com/en/natty/dtc-common there are five dependencies shown as 'Package not available', with no alternative for postfix-tls
The dependecy on postfix-tls is only for the natty version; maverick and oneiric do not have that dependency. Change history for the oneiric version shows +dtc (0.32.10-2) unstable; urgency=low + + * Removed dependency postfix-tls which is removed from SID (Closes: #618379). + + -- Thomas Goirand <z...@debian.org> Tue, 15 Mar 2011 06:23:35 +0000 See also http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=618379 So most probably the dependency on postfix-tls has to be removed from the ubuntu natty version as well. ** Bug watch added: Debian Bug tracker #618379 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=618379 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/789212 Title: Can't install dtc-common package. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
