Error in rustup update nightly

[CatarinaPedreira]

I have a Dockerfile whose parent image is paritytech/ci-linux:974ba3ac-20201006.

When trying to build my dockerfile, the command "RUN rustup update nightly" yields the following error:

`=> ERROR [ 8/12] RUN rustup update nightly

I'm aware this is a problem of compatibility between rustup and docker (the problem lies in the rename() function, more specifically in the fact that docker's filesystem behavior and rustup filesystem's behavior are not compatible) , as per rust-lang/rustup#2542.

The only suggested workaround so far is uninstalling and reinstalling rustup in its entirety, but it seems that nightly already tries to install the most recent version (1.57.0-nightly (51e514c0f 2021-09-12)), so I'm not sure why that works.

Do you have any idea can I go about this in a different way?
