Windows sybsystem for LinuxのSSL/TLSがKasperskyに拒まれる

状況

Windows 10でWSL上のUbuntu 18.04 LTS / 16.04 LTSを使用している環境で、Python環境を作ろうとするとpip等がSSL関連のエラーを返す。ca-certificatesは導入済みで、ping等は疎通する。アンチウイルスソフトとしてKaspersky Free(19.0.0.1088)が導入されている。

curl

USER@local:~$ curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py

wget

仕方がないのでapt-getでインストールする

USER@local:~$ sudo apt-get install python3-pip

インストールは出来るのだが。。。

USER@local:~$ pip3 -V
pip 9.0.1 from /usr/lib/python3/dist-packages (python 3.6)

検索をかけてみるとやはり通信出来ない

USER@local:~$ pip3 search pip

結論から言うとKasperskyの問題

タスクトレイのKasperskyアイコンを右クリックして、settingsを選び、AdditionalからNetworkへ進む。
その中に Encrypted connections scanning というグループがあるので、「 Do not scan encrypted connections 」を選択する。

KasperskyのEncrypted connections scanning停止後は通信できるようになる
