apt-getを使用してboost libをアップグレードする方法は？

私はubuntu 11.04を使用しています。

私のブーストバージョン：

aptツールを使用してboostを1.44+にアップグレードするにはどうすればよいですか？

ありがとう〜

apt-add-repositoryを実行すると、次のように表示されます。

  sam@sam:~/code/ros/pcl$ sudo apt-add-repository ppa:timklingt/ppa
  Error reading https://launchpad.net/api/1.0/~timklingt/+archive/ppa: GnuTLS recv error (-9): A TLS packet with unexpected length was received.
  sam@sam:~/code/ros/pcl$       

それを修正するには？

ありがとう〜

私はlibboost1.46-all-devをインストールしようとします：

これらのエラーはどういう意味ですか？

そしてそれを解決する方法は？

ありがとう〜

編集：Boost-latestは2014年以降更新されておらず、最新バージョンは1.55です

boost-latestPPAは libboostのすべてのバージョンが含まれていますし、私のためにそれを修正しました！

sudo add-apt-repository ppa:boost-latest/ppa
sudo apt-get update

これで、必要なバージョンをインストールできます。執筆時の最新バージョンは1.55です。

sudo apt-get install libboost1X.55-all-dev

残念ながら、Natty（11.04）のリポジトリで利用可能な最新のboostの公式バージョンは1.42です。

これなど、非公式のPPAからインストールしてみてください。

sudo apt-add-repository ppa：timklingt / ppa
sudo apt-get update
sudo apt-get install libboost1.46-all-dev
