Environment
- UBUNTU 16.04
- Odoo 9
Problem
Today I came across the situation where after installing pysftp suddenly I won’t be able to start odoo again. I have tried to do
service odoo restart service odoo stop ; service odoo start
When I have tried to uninstall pysftp, I was having SSL_ST_INIT error
root@erp:~# pip uninstall pysftp

Solution
Step 1: Backup existing directory on OpenSSL and pyOpenSSL from dist-packages folder.
cp -r /usr/lib/python2.7/dist-packages/OpenSSL /tmp/ cp -r /usr/lib/python2.7/dist-packages/pyOpenSSL-0.15.1.egg-info /tmp/
Step 2: Remove directory OpenSSL and pyOpenSSL from dist-packages folder and install pyopenssl module
# rm -rf /usr/lib/python2.7/dist-packages/OpenSSL # rm -rf /usr/lib/python2.7/dist-packages/pyOpenSSL-0.15.1.egg-info # sudo pip install pyopenssl
Step 3: Start odoo service.
