Our builds use germinate to create a custom ISO installer. Germinate attempts to parse all of the index files from an APT repository including Sources. The rustc source package contains restriction formulas which are too new (read as: schema change) for germinate and/or python-apt to understand and it errors out.
If anyone attempted to rebuild rustc using trusty using pbuilder, it won't work for the same reason. (This leads me to conclude that whomever built the binary rustc packages for this trusty backport did not do so on a trusty system). There are zero other content changes required, just removal of the unsupported restriction formulas in the Build-Depends* fields of the control file. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1716047 Title: rustc control file contains unsupported restriction formulas in control file To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/rustc/+bug/1716047/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
