what should ? knowing tried comand conda install -c anaconda lxml=3.6.0 , det massage 

the following packages updated:          conda-env: 2.5.0-py27_0 anaconda --> 2.5.2-py27_0 anaconda  following packages superceded higher-priority channel:      lxml:      3.6.0-py27_0          --> 3.6.0-py27_0 anaconda  proceed ([y]/n)? y  pruning fetched packages cache ... fetching packages ... not connect https://conda.anaconda.org/anaconda/linux-64/conda-env-2.5.2-py27_0.tar.bz2 error: connection error: httpsconnectionpool(host='conda.anaconda.org', port=443): max retries exceeded url: /anaconda/linux-64/conda-env-2.5.2-py27_0.tar.bz2 (caused  newconnectionerror('<requests.packages.urllib3.connection.verifiedhttpsconnection object @ 0x7f7f6c0ac810>: failed establish new connection: [errno -2] name or service not known',)): https://conda.anaconda.org/anaconda/linux-64/conda-env-2.5.2-py27_0.tar.bz2

i see 2 problems reporting:

  1. you have issue internet access anaconda.org. try ping see if down, review connection, and/or see if service temporarily down...
  2. i have tested on anaconda-python3.5 , canopy1.7 (python 2.7) , both, cell works lxml 3.6, , html5lib 0.999. have same lxml seem have different version of html5lib.

your best bet update html5lib, try , update lxml if that's not enough, or report issue continuum if doesn't work. there might incompatibilities between 2 in package resolution. in meanwhile, try anaconda-python3.5, or canopy1.7 if want stay on python2 (see tutorial instructions).
