Hello there, I am experiencing some issues during the installation of deal.ii on ubuntu 20.04. I followed the steps in the manual. When I perform . /candi.sh -p INSTALL_PATH, I got an error:
It looks like your internet connection is not working correctly. You can try this yourself by running wget github.com
wget github.com
Thanks for your answer. I found this to be a common problem, which has been solved by reading (Installation FAQ · geodynamics/aspect Wiki · GitHub).
