Djangoとmod_wsgiのインストールが突然停止しました

Question

django 1.9.6とmod_wsgiを使用してアプリケーションを仮想マシンにインストールするためのスクリプトがあります。それは少なくとも1年間は正常に動作するために使用し、私はそれを使用していない数ヶ月後に - それは突然動作していない。私はいつもきれいなubuntuの信頼できるイメージにインストールしていますが、私は何も変更しませんでした。だから私の推測では、apt-getは別のバージョンのlibapache2-mod-wsgiをインストールしています。

sudo apt-get update 
sudo apt-get install -y python-pip 
sudo pip install django=1.9.6 
sudo pip install python-social-auth 
sudo apt-get -y install apache2 libapache2-mod-wsgi 
... 

私はアプリケーションにApacheサーバを実行しようと、エラーを与える：

それが前に働いていたので、私は実際にはインストールスクリプト以外は何も変更せずにこの問題を解決したいと考えて、それが動作するはずです。

アドバイスはありますか？

セットアップのためのさまざまな要件があり、インストールする追加パッケージを必要とするパッケージの新しいバージョンをインストールしているように見えます。

あなたのコードとデータベースに他の変更を加えなければならない可能性があるため、これまで使用していたものと同じ古いバージョンにパッケージをピン止めすることができます。
