Add the D apt respository in /etc/apt/sources.list.d/dlang.list:
|
|
|
|
deb http://netcologne.dl.sourceforge.net/project/d-apt/ d-apt main
|
|
|
|
Then get the apt key, and install the things:
|
|
|
|
sudo apt-get update
|
|
sudo apt-get -y --allow-unauthenticated install --reinstall d-apt-keyring
|
|
sudo apt-get install dmd-bin dcd dub
