Instruction in the book for toolchain set-up on Debian/Ubuntu fails
An Embedded Rust beginner here! So, please bear with me if the issues I raise are very fundamental and can be easily resolved or is already resolved! :-)
From the page on the book here:
The instruction is to use the following command for installing the toolchain on Debian/Ubuntu:
sudo apt install llvm-dev libclang-dev clang libuv-dev libuv1-dev pkgconf python3-venv python-is-python3
On my Ubuntu 22.10 machine, this is what I get:
sudo apt install llvm-dev libclang-dev clang libuv-dev libuv1-dev pkgconf python3-venv python-is-python3

Package libuv-dev is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
libuv1-dev:i386 libuv1-dev
E: Package 'libuv-dev' has no installation candidate
Here is the output of uname -a:
Linux bluewhale 6.8.0-45-generic #45~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Wed Sep 11 15:25:05 UTC 2 x86_64 x86_64 x86_64 GNU/Linux
I have removed the libuv-dev from the command, and then the installation goes through:
sudo apt install llvm-dev libclang-dev clang libuv1-dev pkgconf python3-venv python-is-python3
Reading package lists... Done
Building dependency tree... Done

The following packages will be REMOVED:

So, I am not stuck. However, I thought I should bring this up, in case the book needs an update, or I am supposed to take a different step.
Thanks for reporting it! We are evaluating how to simplify and unify the installation's instructions
As stated in libudev-sys crate it shall be:
sudo apt-get install libudev-dev
not libuv-dev.
Then the cargo installs work as expected.
Fix proposal https://github.com/esp-rs/std-training/pull/267
