Failed to install cargo-edit 0.9.0 with Rust 1.60 for Ubuntu 20.04.4 LTS (Multipass)

I tried to install cargo-edit 0.9.0 with the following command:

$ cargo install cargo-edit

I get the following compiler error

Caused by:
  could not compile `cargo-edit` due to 2 previous errors

I guess this is newly introduced, as version 0.8.0 installs just fine.
Please let me know if I should provide more detail.
Thank you!

Are you sure you are using Rust 1.60?

• This was compiling in CI before that released
• The impl<'a, const N: usize> Pattern<'a> for [char; N] was merged insta-stable 10 months ago (not noticing it in release notes), so it should have reached stable several releases ago.

@epage Thanks for the quick response.
I think I may have found an issue, but I'm not sure how to resolve it.
I double checked the version I'm using, and it seems that there is some disagreement between rustc and rustup about what I'm actually using. I installed using the curl command on the official website, so I'm not sure why that happened. Do you have any ideas short of reinstalling Rust?

[epage]

What does which rustc say?

[cloudultima3164]

Sorry about the late response.
It says /usr/bin/rustc.

[epage]

So it sounds like you have a distribution-installed rustc and a rustup installed rustc and the distribution-installed one has higher precedence in your PATH but is older.

@epage
Thanks for spending the time to help me out with this, even though it has nothing to do with cargo-edit.
I figured out I had installed rustup with snap, and for some reason again installed it later with the curl command on the official website.
I uninstalled both and then reinstalled with just the curl command - after that cargo-edit 0.9.0 installed without an issue.
Thank you for your patience!
