In my system the problem was dash. Installing ucf was working after "dpkg-reconfigure dash" (choosing "no") and /bin/sh being linked to bash.
Problem seemed to be preinst/postinst scripts which failed when ran with dash. -- package ucf 3.005 failed to install/upgrade: https://bugs.launchpad.net/bugs/210912 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
