Solved the issue - this package is missing some of it's dependencies, which means that it looks like it will fail to install on a non- developer machine (that doesn't have a package-building environment set up).
Steps to solve: 1. Downloaded the source package via "apt-get source dtc-postfix-courier" 2. Tried to build the package using "dpkg-buildpackage -b" 3. dpkg-buildpackage complained that debhelper and po-debconf were missing, so it couldn't build the package. 4. Used apt-get to install debhelper and po-debconf, these also suggested packaged dh-make, curl, wget, lynx, info - which I added to the apt-get install 5. I hadn't removed the non-installing package dtc-postfix-courier and dtc-toaster yet, so the installer tried to complete the installation of these as well. 6. The installation of dtc-postfix-courier was finally successful. I think the problems may be to do with some of those packages that were needed to be able to do a package build - the full list of packages added in that step was: debhelper po-debconf dh-make cvs rsync bazaar info curl wget lynx intltool-debian html2text gettext dtc-postfix-courier dtc-toaster -- dtc-postfix-courier fails during --configure, can't install https://bugs.launchpad.net/bugs/160847 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
