Install.sh traceback installiing Python Components #34

Closed Dave-Mack closed 8 months ago

Dave-Mack commented 8 months ago

Running Vagrant using bento/ubuntu-20.04 box. Cloned NetOpsWokshot git repo and attempted running install.sh in install directory. I am getting tracebacks when it attempts to install Python Components.

Looks related to OpenSSH:

File "/usr/lib/python3/dist-packages/OpenSSL/__init__.py", line 8, in <module>
    from OpenSSL import crypto, SSL
  File "/usr/lib/python3/dist-packages/OpenSSL/crypto.py", line 1553, in <module>
    class X509StoreFlags(object):
  File "/usr/lib/python3/dist-packages/OpenSSL/crypto.py", line 1573, in X509StoreFlags
    CB_ISSUER_CHECK = _lib.X509_V_FLAG_CB_ISSUER_CHECK
AttributeError: module 'lib' has no attribute 'X509_V_FLAG_CB_ISSUER_CHECK'
`

Full Traceback below:

vagrant@vagrant:/vagrant/NetOpsWorkshop/install$ ./install.sh 
Ansible/NAPALM/pyATS installation script
=====================================================================
This script updates your system, installs additional APT and PIP
packages, and installs Ansible, NAPALM, pyATS and ntc-templates

The script was adapted for and tested on Ubuntu 20.04. Do not use it
on earlier versions of Ubuntu.

NOTE: the script is set to abort on first error. If the installation
completed you're probably OK even though you might have seen errors
during the installation process.
=====================================================================
Update installed software to latest release (might take a long time)
Install missing packages (also a pretty long operation)
Extracting templates from packages: 100%
Install nice-to-have packages
Install Python development and build modules
Installing NAPALM dependencies
Install baseline Python components
Install Ansible Python dependencies
.. pynacl
.. paramiko netmiko
Install optional Python components

Followed steps here to fix PIP3 and OpenSSL: https://stackoverflow.com/questions/73830524/attributeerror-module-lib-has-no-attribute-x509-v-flag-cb-issuer-check

Thank you. I know I encountered similar problems in netlab project. Will figure out how I solved it there and apply the fix to the installation script.

Took me half a day to find the combo that works on 20.04 and 22.04 :(( but it works on fresh Ubuntu VMs now.

Thanks again for reporting this!
