I use raspberry pi 3b jessie distribution. I am trying to update my raspberry but it gives me this error:

sudo apt-get update

Get:1 http://archive.raspbian.org jessie InRelease 100% [1 InRelease gpgv 6,893 B]Splitting up /var/lib/apt/lists/partial/archive.r
Ign http://archive.raspbian.org jessie InRelease data and signature failed E: GPG error: http://archive.raspbian.org jessie InRelease: Clearsigned file isn
't valid, got 'NODATA' (does the network require authentication?)

And also when I tried to download python packages through pip, it shows:

sudo pip install 'pyglet' Downloading/unpacking pyglet Cannot fetch index base URL https://pypi.python.org/simple/ Could not find any downloads that satisfy the requirement pyglet Cleaning up... No distributions at all found for pyglet Storing debug log for failure in /root/.pip/pip.log.

Could somebody please point me out where I'm doing wrong?

Possibly your internet provider is running a 'transparent proxy' that is interfering with apt-get

  • I have tried with another internet provider, but still same.Could i somehow bypass this? Or alternative methods? – adrian.andreas May 07 '17 at 18:18
  • I even used http://whatismyip.network/proxy-check-tool-detect-how-isp-transparent/ and said that the provider does'nt use transparent proxy – adrian.andreas May 07 '17 at 18:28
