Initial install issue on SDK 2.0.0 - "error: RPC failed; curl 92 HTTP/2 stream 0 was not closed cleanly: CANCEL (err 8)"

[dshadoff]

I am running a Raspberry Pi 400, and have been using pico-setup to reinstall the pico repositories on each release, but I have had multiple issues with the 2.0.0 release.

The first issue during install is "error: RPC failed; curl 92 HTTP/2 stream 0 was not closed cleanly: CANCEL (err 8)". This issue APPEARS to be recoverable, in that re-running the ./pico-setup.sh script will get past this point (until it hits a later issue which does not appear to be related).
This error has never happened with past versions.

For context, I am running a Raspberry Pi 400, and "uname -a" provides the following output:

Linux raspberrypi 5.10.103-v7l+ #1529 SMP Tue Mar 8 12:24:00 GMT 2022 armv7l GNU/Linux

(I will file a separate issue for the subsequent error, as it does not appear to be related.)

I don't see anything obvious indicating that my system is missing any new pre-requisites.

Here is more context for the RPC failed error output:
