issues with updating anaconda and installing new packages #3929

mohelm · 2016-11-21T20:49:48Z

Hi I am getting this report when trying to install seaborn on anaconda with python 3.5. Any ideas/help would be greatly appreciated. Many thanks

Edit I am getting the below error also when doing:

Can you try downgrading requests? conda install requests=2.11

We just fixed another issue that popped up with the requests upgrade. A little frustrating.

Here also I guess the output of conda config --show-sources would be useful.

And @apsey, you missed the whole stack trace in your bug report. I can't do much without the stack trace 😜

Many thanks, for the reply.

conda config --show-sources
shows nothing?

kalefranz · 2016-11-22T20:55:39Z

conda config --show-sources shows nothing?

Ok. Just means you have all of the default settings.

What version of pyopenssl does conda list show? Can you try

conda update pyopenssl

and if that doesn't work maybe

CONDA_SSL_VERIFY=false conda update pyopenssl

mohelm · 2016-11-22T21:01:11Z

many thanks again. the latter seems to work (but not the former):

Package plan for installation in environment /home/moritz/Python/anaconda3:

The following packages will be downloaded:

package                    |            build
---------------------------|-----------------
cffi-1.5.2                 |           py35_0         327 KB
conda-4.2.13               |           py35_0         402 KB
cryptography-1.5.3         |           py35_0         800 KB
pyopenssl-16.2.0           |           py35_0          70 KB
------------------------------------------------------------
                                       Total:         1.6 MB

The following packages will be UPDATED:

cffi:         1.2.1-py35_0  --> 1.5.2-py35_0 
conda:        4.2.12-py35_0 --> 4.2.13-py35_0
cryptography: 1.0.2-py35_0  --> 1.5.3-py35_0 
pyopenssl:    0.15.1-py35_1 --> 16.2.0-py35_0

I suppose I proceed with the update, right?

kalefranz · 2016-11-22T21:09:10Z

ahhhh, the issue is an old cryptography version.

Yes, proceed. And then you shouldn't run into the problem again.

That's an anaconda.org read timeout. Should be spurious. But glad to have the report.

If conda config --show-sources is empty output for you, then I have a bug somewhere. You've definitely added the r channel to your configuration somewhere. That's the channel that's triggering your timeout on anaconda.org.

It is running on a dockerfile build. The conda config --show-sources ran before the add-channel command.

Also, after a while, I could build, so my issue is gone too. Thanks!

Hi!
I have the same problem on Windows. I try to install photutils or update conda and it does not work.
What can I do?
(sorry for pictures, but I am not acquinted with windows and I do not know how to copy it from terminal)

tpsanjan · 2017-01-03T03:34:25Z

Hi,

I am getting a similar error "Fetching package metadata ... An unexpected error has occurred" for most of the commands that I tried such as

conda update conda
conda update scikit-learn (This is what I was trying to do)

Following the suggestions given in the above posts, I tried these:

downgrading the requests using

conda install requests=2.11
Throws the same error "Fetching package metadata ... An unexpected error has occurred"

Verify the output of conda config --show-sources
Shows nothing => I have all of the default settings (Green signal !)
What version of pyopenssl does conda list show?
Unfortunately, I don't have it installed (Should I be checking in the root env instead?)

conda install pyopenssl
Throws the same error "Fetching package metadata ... An unexpected error has occurred"

conda update pyopenssl
Throws the same error "Fetching package metadata ... An unexpected error has occurred"

CONDA_SSL_VERIFY=false conda update pyopenssl
Error: 'CONDA_SSL_VERIFY' is not recognized as an internal or external command,
operable program or batch file.

Also, I don't have any 'r' channel which might be triggering the timeout. So, I would like to know how to troubleshoot this error.

I have been using conda for almost 6 months and had never encountered this error before. I am running it on Windows 7 (64-bit) OS.

Here's the output for conda update scikit-learn command:

Hello Friends
I have solved the problem.

This error cause because of different version of python in anaconda and installed python on your system.

when you upgrade anaconda to new version, It has been written in newest version on pyhton (3.6 for me) but i have installed lower version (3.5 for me) of python in my system, so it cause fail in run.

so download newest version of python and install it, then
rename folder of last python to a different name such as "pythoonn"

then conda command will works.
