  • What is this 'conda' command you're using? – Anders Olsson Jan 27 '16 at 08:59
  • Conda is an open source package management system and environment management system for installing multiple versions of software packages and their dependencies and switching easily between them. [link] (http://conda.pydata.org/docs/) – Mobeen Jan 27 '16 at 09:05
  • Did you install conda from the official Ubuntu repos? Otherwise, it's hard to see this a Ubuntu question, that should be handled in this community. BTW, did you try the command the help text hinted to: `conda create -n my_root --clone=/home/ws2/anaconda2`? – Anders Olsson Jan 27 '16 at 09:32

The problem was that somehow "anaconda2" folder where "anaconda" is installed, was set to 'access only' because the owner of "anaconda2" folder was "root". Now I have changed the ownership of "anaconda2" folder by using command

sudo chown -R ws2 anaconda
sudo chown -R usr foldername

follow the following commands and work accordingly whenever there comes an issue related to these permission. what i have done here is i changed the permission of all files and subfolders of 'pkgs' folder in anaconda directories. sudo chown -R 'user': /home/user/anaconda/pkgs

this worked for me in your case do

sudo chown -R ws2: /home/ws2/anaconda2

Please try running your command using sudo, like this:

  sudo conda install opencv

    conda doesn't work with sudo – Mobeen Jan 31 '16 at 09:50
  • You can make this work with a root user, you usually just need to provide the correct `PATH` for the root user, using `sudo env "PATH=$PATH" conda install ...`. If you aren't sure what this is doing, probably best not to use it! – n1k31t4 May 25 '17 at 12:26
