Build sd image failed

Last week I successfully build the SD image but for this week, when I make the sd image, a lot of things are downloaded. And the the following issue occurs:
make[1]: Entering directory ‘/home/jason/PYNQ/sdbuild/build/gcc-mb’
/usr/local/bin/ct-ng:223: /usr/local/bin/scripts/ No such file or directory
make[1]: *** No rule to make target ‘/usr/local/bin/scripts/’. Stop.
make[1]: Leaving directory ‘/home/jason/PYNQ/sdbuild/build/gcc-mb’
make: *** [/home/jason/PYNQ/sdbuild/packages/gcc-mb/Makefile:29: /home/jason/PYNQ/sdbuild/build/gcc-mb/native/arm-unknown-linux-gnueabihf] Error 2

Is there some bugs in the latest update? How to solve the problems?
