conda stuck on Proceed ([y]/n)? when updating packages in ipython console

Question

I just downloaded Anaconda 4.2.0 (with python 3.5.2) for Mac OS X. Whenever I try to update any packages etc, my ipython console presents the package dependencies and displays "Proceed ([y]/n)?" but does not take any inputs. E.g. I press enter, or y-enter etc. and nothing happens. Here's an example:

!conda create -n graphlab-env python=2.7 anaconda
Fetching package metadata .......
Solving package specifications: ..........

Package plan for installation in environment /Users/Abhijit/anaconda/envs/graphlab-env:

The following packages will be downloaded:

    package                    |            build
    ---------------------------|-----------------
    python-2.7.12              |                1         9.5 MB

The following NEW packages will be INSTALLED:

    _license:           1.1-py27_1         
    _nb_ext_conf:       0.3.0-py27_0       
    alabaster:          0.7.9-py27_0       
    anaconda:           4.2.0-np111py27_0  
    anaconda-clean:     1.0.0-py27_0       
.

.
    yaml:               0.1.6-0            
    zlib:               1.2.8-3            

Proceed ([y]/n)?

It won't respond after this step. When I enter 'Ctrl-C' it breaks out of this loop. I have tried Shift-Enter, Alt-Enter, Ctrl-Enter, Cmd-Enter etc but no luck. Tearing my hair out over this. Am I missing something?

Did you check your internet connection, or may be the package you are trying to download is not available right now. — Md Sirajus Salayhin, Oct 03 '16 at 09:48
Internet connection is fine. This happens with every update where it displays the 'Proceed?' part. For a single package update where the Proceed? part is not shown i.e. when it does not need any input, it works without any problems. I have updated and re-installed Anaconda multiple times and this has not solved the issue. — Aby, Oct 03 '16 at 13:23
Just started running into this issue with a fresh install of Anaconda. Moreover, it *really* hangs on `conda install jupyter` even when passing `-y` — MattR, Jun 24 '17 at 18:48

You can launch shell commands with the ! operator in ipython, but you can't interact with them after the process has launched.

Therefore, you could:

execute your conda command outside of your ipython session (IOW, a normal shell); or
pass the --yes flag. e.g.:

!conda create -n graphlab-env python=2.7 anaconda -y

Add --yes at the end of the command.

For example:

%conda install --yes seaborn

fyi `pip uninstall pipupgrade --yes` also works for pip users – Kermit Jul 02 '19 at 16:05

Solution:

!conda update --update-all --yes

or shortly:

!conda update --all -y

Just Append -y to any command to say yes to all the yes/no questions. Most of the packages are configured in a way to work with this. For your:

!conda create -n graphlab-env python=2.7 anaconda -y
