solution

I have check the nightly version installed. The I check the web and find out there is no the 'nightly-2021-04-25'. As far as I know, the nightly is very new version beyond stable. So I think the new one should work. Then I see the file named rust-toolchain with git history. It seems that it alway change for the nightly version. So I just change it to the new one.

- channel = "nightly-2021-04-25"
+ channel = "nightly-2021-06-27"
$ cargo --version

expect

can the nightly version just let it be null? it should be smart to know its newest version.

Hi,

we are currently pinning the nightly to a specific version in the rust-toolchain file. This is done for (i) keeping it consistent between tutorials and users, and (ii) recently also because newer nightlies are incompatible with some dependencies we have in later tutorials (tock-registers doesn't compile on newer nightlies yet. A new release is due soon, though.

The Github Actions of this tutorial check every night if downloading the pinned nightly works, and it worked for this night too: https://github.com/rust-embedded/rust-raspberrypi-OS-tutorials/actions

I plan to stay at the pinned nightly until the new tock-registers release is out and I had time to switch to it.

It is very nice for your reply. Now I know why. Thank you all the time.

By the way, cause I use TUNA as a rustup mirror. And they just keep nightly for a while. This is the reason why I can't down the version of nightly-2021-04-25-x86_64-unknown-linux-gnu. So just cancel the TUNA mirror for now before download the nightly-2021-04-25.
