Well, I swear I never had to do all these setting with build-gnuradio
script :D
It was a peace meal !

This is working :

proxies = {"http":"http://proxy.iiit.ac.in:8080","https":"
http://proxy.iiit.ac.in:8080","HTTP":"http://proxy.iiit.ac.in:8080
","HTTPS":"http://proxy.iiit.ac.in:8080"}

r = requests.get(images_url, stream=True, headers={'User-Agent': 'UHD
Images Downloader'}, proxies=proxies)

but this is not :

proxies = {"HTTP":"http://proxy.iiit.ac.in:8080","HTTPS":"
http://proxy.iiit.ac.in:8080"}

r = requests.get(images_url, stream=True, headers={'User-Agent': 'UHD
Images Downloader'}, proxies=proxies)

Where can I get the old version of uhd_image_downloader.py Just want to
check

Meanwhile here is my environment :

sumit at sumit-ThinkCentre-M72e:/usr/local/lib/uhd/utils$ cat /etc/environment
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/usr/local/lib/uhd/images:/usr/local/share/uhd/images"
http_proxy="http://proxy.iiit.ac.in:8080/"
https_proxy="https://proxy.iiit.ac.in:8080/"
ftp_proxy="ftp://proxy.iiit.ac.in:8080/"
socks_proxy="socks://proxy.iiit.ac.in:8080/"
UHD_IMAGES_DIR="/usr/local/lib/uhd/images"
