I would like to install the latest Boost C++ libraries onto my 10.10 system using a PPA but cannot find one that works. Nordlöw already suggested good sources in a similar discussion but I could not install the library. The installer states that I have the latest version running.
The ppa:purplekarrot by Daniel Pfeiffer does not upgrade my current 1.42 installation. 
Although I try to follow the exact instructions by fossfreedom there are no packages listed to being upgraded when I run sudo apt-get upgrade. Here is the output log.
When I try to install libboost-filesystem the only tab completions I am offered are the following.
⚡ sudo apt-get install libboost-filesystem
libboost-filesystem1.40.0 libboost-filesystem1.42.0 libboost-filesystem-dev
libboost-filesystem1.40-dev libboost-filesystem1.42-dev

sudo apt-get install libboost-filesystem-dev? – fossfreedom♦ Dec 15 '11 at 11:47
