This appears to be related to https://bugs.launchpad.net/ubuntu/+source/rootstrap/+bug/130640
That bug refers to Ubuntu's refusal to install rootstrap (for reasons that aren't entirely clear from the refusal). Either putting rootstrap back in the repository or removing the rootstrap dependency from pbuilder-uml would resolve this bug. From the bug above, the latter appears to have a greater chance of success. -- pbuilder-uml (0.161ubuntu2) depends on rootstrap(>= 0.3.9-1) and user-mode-linux which are notr installable in feisty https://bugs.launchpad.net/bugs/106949 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
