Eu rodei o sudo apt-get update e ele ficou preso nesse ponto. Antes disso, eu corri os seguintes comandos para instalar o pycharm.
echo "deb http://archive.getdeb.net/ubuntu $(lsb_release -cs)-getdeb apps" | sudo tee /etc/apt/sources.list.d/getdeb-apps.list
wget -q -O- http://archive.getdeb.net/getdeb-archive.key | sudo apt-key add -
G580:~$ sudo apt-get update
