Failed to install

AI-generated summary

The user Deveroonie encountered a failure during Discourse installation, with an error indicating the system could not resolve the host github.com. Falco identified this as a DNS issue within the Docker container, despite the host having connectivity, as the user could successfully clone the repository. Ed_S clarified that the git clone occurs on the host, while subsequent actions run in the container, and suggested checking DNS resolution inside the container using ping and potentially adjusting the Docker interface MTU, referencing a similar issue on Discourse Meta here.

Error is

fatal: unable to access 'https://github.com/discourse/discourse.git/': Could not resolve host: github.com

Your host or containers have internet connectivity problems.

i managed to git clone it fine tho…

The git clone action is taken in the host, so that shows the host is OK, but the subsequent actions take place in the container. If they fail, it indicates trouble within the container (docker) and in this case, DNS (name resolution) trouble.

There have been situations before where people report this kind of connectivity problem inside docker. Perhaps see

It might be useful to have details of your provider and the location. It might be useful to test inside the container using commands something like this:

./launcher enter app 
ping -c2 github.com
exit
