I am trying to build an image for Zedboard using PYNQ. However, I am getting the following error: ``` make PREBUILT=/home/nairit/Xilinx/pynq_rootfs_arm_v2.5/bionic.arm.2.5.img BOARDS=Zedboard /opt/qemu/bin/qemu-arm-static -version | fgrep 4.0.0 qemu-arm version 4.0.0 vivado -version | fgrep 2019.1 Vivado v2019.1 (64-bit) xsdk -version | fgrep 2019.1 ****** SDK v2019.1 (64-bit) which petalinux-config /home/nairit/opt/Xilinx/PetaLinux/2019.1/tools/common/petalinux/bin/petalinux-config which arm-linux-gnueabihf-gcc /home/nairit/opt/Xilinx/SDK/2019.1/gnu/aarch32/lin/gcc-arm-linux-gnueabi/bin/arm-linux-gnueabihf-gcc which microblaze-xilinx-elf-gcc /home/nairit/opt/Xilinx/PetaLinux/2019.1/tools/xsct/gnu/microblaze/lin/bin/microblaze-xilinx-elf-gcc which ct-ng /opt/crosstool-ng/bin/ct-ng which python | fgrep /usr/bin/python /usr/bin/python sudo -n mount > /dev/null bash /home/nairit/PYNQ/PYNQ/sdbuild/scripts/check_env.sh Pass: Current OS is supported.

I am using Vivado, SDK and Petalinux 2019.1 and latest PYNQ cloned using: ``` git clone https://github.com/Xilinx/PYNQ.git ``` I am using a prebuilt **[PYNQ rootfs arm v2.](http://bit.ly/33fftBw)** [**5**](http://bit.ly/33fftBw) image file and the Petalinux BSP **avnet-digilent-zedboard-v2019.1-final.bsp** downloaded from Xilinx. I created a folder Zedboard inside which I put the BSP file and a **Zedboard.spec** file. The contents of the **Zedboard.spec** file are: ```auto ARCH_Zedboard := arm BSP_Zedboard := avnet-digilent-zedboard-v2019.1-final.bsp BITSTREAM_Zedboard := STAGE4_PACKAGES_Zedboard := pynq boot_leds ethernet ``` I tried running the codes: ```auto make PREBUILT=/home/nairit/Xilinx/pynq_rootfs_arm_v2.5/bionic.arm.2.5.img BOARDS=Zedboard ``` and ```auto ./scripts/image_from_prebuilt.sh Zedboard /home/nairit/PYNQ/PYNQ/boards/MyBoards/Zedboard/avnet-digilent-zedboard-v2019.1-final.bsp arm /home/nairit/Xilinx/pynq_rootfs_arm_v2.5/bionic.arm.2.5.img ``` but end up with the same error. **Can someone please help?** ---

I set the default python to 3.6 when setting up the OS. Switching default python to 2.7 solved it. `sudo update-alternatives --config python`
