Thanks for taking your time to report this issue and help making Ubuntu better.
I've marked this with the "ftbfs" tag used for build failures (fails-to- build-from-source). I notice there's a newer version of this package in artful-proposed (https://launchpad.net/ubuntu/+source/rustc/1.18.0+dfsg1-4) which might resolve this issue, however that is currently failing to build on armhf. ** Tags added: ftbfs -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1707915 Title: rustc couldn't be rebuilded To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/rustc/+bug/1707915/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
