I have already installed the pyenv on my system, and the command
pyenv install --list goes well. But when I download some Python versions using
pyenv install 2.7.11, it turns out as follows:
Downloading Python-2.7.11.tgz... -> https://www.python.org/ftp/python/2.7.11/Python-2.7.11.tgz error: failed to download Python-2.7.11.tar.gz BUILD FAILED (Ubuntu 15.04 using python-build 20160509)
I didn’t find any similar problem on the official Common build problems.
Is it that
pyenv didn’t catch the new Ubuntu update?
pyenv install -v 2.7.11 gave me a similar error.
Installing the pyenv requirements solved my issue :
sudo apt-get install -y make build-essential libssl-dev zlib1g-dev libbz2-dev libreadline-dev libsqlite3-dev wget curl llvm libncurses5-dev libncursesw5-dev xz-utils tk-dev
pyenv install 2.7.11
To install python by using
pyenv, the command
pyenv install -v 2.7.11 could show more message than
pyenv install 2.7.11. So it will be easy for me to locate the error. This time I got
curl: (77) error setting certificate verify locations: CAfile: /etc/pki/tls/certs/ca-bundle.crt CApath: none
This problem has already been solved in curl: (77) error
# sudo apt-get install ca-certificates
The issue was that curl expected the certificate to be at the path
/etc/pki/tls/certs/ca-bundle.crt but could not find it because it was at the path
Copying my certificate to the expected destination by running
sudo cp /etc/ssl/certs/ca-certificates.crt /etc/pki/tls/certs/ca-bundle.crt
worked for me. You will need to create folders for the target destination if they do not exist by running
sudo mkdir -p /etc/pki/tls/certs
If needed, modify the above command to make the destination file name match the path expected by curl, i.e. replace
/etc/pki/tls/certs/ca-bundle.crt with the path following “CAfile:” in your error message.
The default installing curl don’t support https protocol. You can check with “curl –version”. you can find http but no https.
So you need to reinstall curl refering how to install curl and libcurl.
./configure --prefix=$YOUR_DIR --with-ssl make make install
or find where you install the ssl for example /opt/OpenSSL
I was facing a similar issue. I was using the fedora 29 and trying to install the python 2.7.5. Below was the error output.

I was searching for a solution then stumbled upon this thread.. which says:–
issue was a longstanding in Python < 2.7.15, and recently triggered with recent compiler. They fixed it in 3.x, and backported into 2.7.15. So instead of just gathering the patch back, maybe it’s best to update our 2.x version to 2.7.15 with the cross compilation patches. I’m a little bit afraid of the implication (ssl certificates issues on 2.7.x at some point).
I tried installing 2.7.15 with
pyenv install 2.7.15 and it installs without errors.
