I get the same problem when installing from Ubuntu 19.04:

(base) joe@phil:~$ sudo apt install python3-graph-tool

Only libboost-*1.67.0 seems available in the Ubuntu apt repository (indeed, 1.67.1 never seems to have been officially released: https://www.boost.org/users/history/)

The problem ist, that when I try to install via "sudo apt-get install python3-graph.tool", I get:

What do I do now?

Cheers

Thanks for the fast answer!

Now I have the issue, that graph-tool needs dependencies that I can't get by
using "/sudo apt-get .../.".

In particualar: He wants a newer version of boost than the one I get by
"/sudo apt-get install libboost-all-dev/".

Is this intended?

The necessary dependencies should be installed automatically when you
install the package. There is no need to install them individually by hand.

Best,
Tiago
