The LDC Travis CI builds depend on the llvm.org APT repositories and have started to fail regularly while trying to obtain the packages from llvm.org/apt. The packages are sometimes unavailable. For example at the moment, llvm-3.9_3.9~svn270380-1~exp1_i386.deb is available but not llvm-3.9_3.9~svn270380-1~exp1_amd64.deb, and so the build is broken.
Could this be related to the (afaik) recent change in update frequency? I thought that before the packages were updated once a week, but now they are updated once a day (or even more frequent). For us, this high update frequency is not needed and updating once a week would be much nicer (we try to keep a manually-built Windows LLVM package in-sync with the APT revision).
Another cause of the problem may be that the APT packages seem to have changed from amd64 to i386.
Thanks a lot for helping to resolve the Travis failures,
