ZERO Install XML Feed file read error

[niranjancareio]

Hi
I am facing an issue "input stream closed, unable to get user input" when try to read XML feed file using below code
selections = Solver.Solve(requirements);
My XML feed file is on Azure
If I keep XML feed file on local machine it executes above statement without any error.
Please suggest.

Note: I was able to read file and get selections earlier with same code. Recently I have added few setups in my installer so I wanted to have new Feed XML using which I can download new dependancies.

When using a local file path for a feed, Zero Install does not check for signatures. But when using an HTTP(S) URL, the feed needs to be signed and the user needs to trust the signature’s key.

The message “input stream closed, unable to get user input” indicates that Zero Install tried to ask the user via the terminal whether they want tot trust the key but failed, probably because the app was running in a non-interactive environment like a CI sever.

You can also trust a key in code like this to avoid the user prompt:

var services = new ServiceProvider(…);
services.TrustDB.TrustKey("ABC123", new Domain("example.com"));
services.TrustDB.Save();
var selections = services.Solver.Solve(requirements);
