Como atualizar o boost para 1.44+ usando as ferramentas apt?

Obrigado ~

Quando executo o apt-add-repository, ele mostra:

  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$       

Como corrigi-lo?

Obrigado ~

O que esses erros significam?

E como resolver isso?

EDIT: Boost-latest não está sendo atualizado desde 2014 e a versão mais recente é 1,55

O boost-latestPPA contém todas as versões do libboost e o corrigiu para mim!

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

agora você pode instalar a versão desejada, a última versão neste momento é 1,55:

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

Infelizmente, a versão oficial mais recente do boost disponível nos repositórios do Natty (11.04) é 1.42.

Você pode tentar instalá-lo a partir de um PPA não oficial, por exemplo, este.

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