OS Catalina Recovery mode: "Downloading installer information to the target volume failed"
I am having the exact same problem. Something weird that helped me past the &quot;downloading instaler information...failed&quot; is using different wireless connections, and retrying many times. Some (magical) times it just passes to the next screen. This is very weird, I know, but it helped in my case. When I get passed that error, I find a different one: the installation gets a timeout around 90% of the installation. I have probably the same computer as you, Macbook pro 2019, 16 inches, 8core base model with T2. Please let me know if you find a solution as I am in the same condition as you. I will let you know if I find a solution too. What I will try is continue trying on different wifi connections and let you know. I am 1000 miles away from an Apple store too (at a mountain village in Argentina). God help us, hahaha!
