Hi,
I'm new to both graph-tool and Ubuntu, which I'm installing it on (as a
virtual machine on my Windows 10 computer).
I've downloaded graph-tool 2.27 in my 'downloads' folder, and then followed
the install instructions at
https://git.skewed.de/count0/graph-tool/wikis/installation-instructions:
Installation via package managers
However, this produces some error messages. Do I need to locate some or all
of the files I downloaded onto a specific location on my virtual machine?
Here's the output I get:
VirtualBox:/etc/apt$ sudo apt-get update
