Summary of the issue you are facing:

I would like to install several core apps, notably the “Contacts” app. My server is however purely using IPV6 without any IPV4 support. Unfortunately, the app is hosted on GitHub, which does not support IPV6 in the year of our lord 2026 (thanks a lot GitHub).

Consequently, when I click “Download and enable“ I get a curl error stating that the network is not reachable. This is however not a problem / bug in nextcloud, when I enter ping github.com on the console I get an error message of ping: connect: Network is unreachable.

My idea for a workaround would be to download the file manually to my local machine, copy it over onto my server, and then install it. Problem is that I don’t see any way to install an app file either on the web interface or using occ.

Do you have any ideas on how to install the required apps on my machine anyways?

cURL error 7: Failed to connect to github.com port 443 after 0 ms: 
Couldn't connect to server (see

It is a shame how a company that endlessly talks about Ai is to incompetent to implement IPv6, at least at the edge.

NAT64 might help you.

My workaround would be to not use a server that doesn’t support IPv4 at all. Complaining that it’s 2026 won’t help. There will probably still be IPv4-only services on the internet in 2036. :wink:
