JFYI, trying to produce a dockerized Iroha locally running M1 processor (step 17/19)
> [builder 5/5] RUN cargo build $PROFILE --workspace:

#17 24.80 error: failed to run custom build command for iroha_client v2.0.0-pre-rc.3 (/iroha/client)
#17 24.80
#17 24.80 Caused by:
#17 24.80   process didn't exit successfully: /iroha/target/debug/build/iroha_client-14d71321ee6f1108/build-script-build (exit status: 101)
#17 24.80   --- stderr
#17 24.80   error: toolchain 'nightly-2022-04-20-aarch64-unknown-linux-gnu' is not installed

installing the toolchain locally obviously does not help

as an idea for the future, we might provide some flexibility for the build process to determine and install the toolchains etc needed depending on the host configuration

This is a known problem resolved by this PR (https://github.com/hyperledger/iroha/pull/2168).

Interesting, I pulled the change and the cause remained the same, though a step and the lines around changed

Bogdan Mingela, [29.04.22 17:08]
ah, it's not the same, it requires also
toolchain 'nightly-2022-04-20-x86_64-unknown-linux-gnu' is not installed
now

Maybe this will help (it helped me). I saw this problem and fixed it this way.
