Caused by:
  feature `edition2021` is required

  The package requires the Cargo feature called `edition2021`, but that feature is not stabilized in this version of Cargo (1.55.0 (32da73ab1 2021-08-23)).
  Consider trying a newer version of Cargo (this may require the nightly release).
  See https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#edition-2021 for more information about the status of this feature.

Thanks for giving this a shot Kristaps. Rust edition 2021 is v1.56, so 1.55 won't compile. Upgrade to rust 1.56+

[kristapsk]

Ok, will try. Need to figure out details about Ubuntu. For some reason I have rustc 1.55 in /usr/local/bin and 1.61 in /usr/bin, with /usr/local/bin being first on PATH.

But README needs to be updated, it currently says about requirements "Rust version 1.48 or higher to compile".

[DanGould]

Thanks for the readme catch, too. You should be able to use rustup update stable to change your toolchain to edition 2021

I have 1.61 with apt install cargo. Just did chmod -x /usr/local/bin/cargo* /usr/local/bin/rust*. Not even sure why they are there, likely leftover from some tests.

[DanGould]

Were you able to build? Is this issue resolved? The readme is

[kristapsk]

Yes.
