Certbot: Certbot Python के पुराने संस्करण का उपयोग करता है

हाय सब, उबंटू 14.04 पर सर्टबॉट पिप (8.0.3) के पुराने संस्करण का उपयोग करता है, भले ही पिप (9.0.1) का नवीनतम संस्करण उपलब्ध हो। मैं सफलता के साथ $certbot-auto नवीनीकरण कमांड नहीं चला सकता, क्योंकि यह InsecurePlatformWarning चेतावनी देता है। क्या मैं इसे ठीक कर सकता हूँ? नीचे मैंने सभी आउटपुट चिपकाए:

Certbot has problem setting up the virtual environment.

Based on your pip output, the problem can likely be fixed by 
increasing the available memory.
