操作手順

参考URL:http://qiita.com/cm3/items/5e200b0ac8f1e76436f0
http://www.ubuntu.com/usn/usn-2165-1/

  1. pinternサーバのopensslのバージョン確認
$ openssl version
OpenSSL 1.0.1 14 Mar 2012

2.Ubuntuのバージョンも確認

$ cat /etc/lsb-release
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=12.04
DISTRIB_CODENAME=precise
DISTRIB_DESCRIPTION="Ubuntu 12.04.2 LTS"

3.変更前のopensslの状態

$ dpkg -l | grep openssl
rc  libgnutls-openssl27              2.12.14-5ubuntu3.4           GNU TLS library - OpenSSL wrapper
ii  openssl                          1.0.1-4ubuntu5.9             Secure Socket Layer (SSL) binary and related cryptographic tools

4.opensslのアップデート

sudo apt-get update
sudo apt-get install openssl libssl1.0.0
sudo reboot
dpkg -l | grep openssl
$ dpkg -l | grep openssl
rc  libgnutls-openssl27              2.12.14-5ubuntu3.4           GNU TLS library - OpenSSL wrapper
ii  openssl                          1.0.1-4ubuntu5.12            Secure Socket Layer (SSL) binary and related cryptographic tools

補足

openssl更新後・・・

$ openssl version
OpenSSL 1.0.1 14 Mar 2012

になってても

$ dpkg -l | grep openssl
rc  libgnutls-openssl27              2.12.14-5ubuntu3.4           GNU TLS library - OpenSSL wrapper
ii  openssl                          1.0.1-4ubuntu5.12            Secure Socket Layer (SSL) binary and related cryptographic tools
