Hi there,

I'm trying to install Manalyze following the instructions on the documentation in the Linux section.
uname -a
Output:
Linux 4.18.0-17-generic #18~18.04.1-Ubuntu SMP Fri Mar 15 15:27:12 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

When I run sudo cmake . I get the following error stacktrace:

Hi! I thought I had replied to this, but if you read the log you'll see the following message: Could not resolve host: github.com.
Looks like a network problem on your end.
