What does it mean by "foundered over financial terms and demands" in this sentence? [closed]

Could you please read the paragraph (incomplete) and tell me your answer?

This is an excerpt from an article on The Economist "Why does Tata Group want Air India back?"—

"In recent years it was losing nearly $3m a day. Operating costs far exceed the industry average. So do customer complaints. Perhaps realising this, the government began trying to offload Air India in 2001, but deals repeatedly foundered over financial terms and demands that the state retain a residual stake, and possibly residual control."

And my question is: what does the word "deals", and phrases "foundering over" and "financial terms" mean here? Also, could you please tell me what part does "demands" play in this sentence?

Solution 1:

A ship at sea founders when it sinks or hits the shore badly, particularly coming aground against rocks that break the hull of the ship. The word is being used in your case in a similar way. The deals, agreements, that are proposed founder that is fail or break apart on the harsh realities, the financial terms or conditions, of the state's demands, that is their requirement of a residual stake or control.

But agreements repeatedly fail because of financial requirements and demands that the state retain a residual stake, and possibly residual control."
