I followed the installation instructions in the website:
https://git.skewed.de/count0/graph-tool/-/wikis/installation-instructions
for installing graph-tool on Ubuntu 18.04, but when I write "sudo apt-get
install python3-graph-tool" in the terminal, it gives me the following
error:
Reading package lists... Done
Building dependency tree
Reading state information... Done
