cargo-generate install fail on Ubuntu 20.04

Trying to install cargo-generate on Ubuntu 20.04.1 LTS, first it complained about ssl, installed libssl with this command sudo apt-get install -y libssl-dev but now getting the error below.

How can I install cargo-generate on Ubuntu 20.04?

rustc --version
rustc 1.49.0 (e1884a8e3 2020-12-29)

cargo --version
cargo 1.49.0 (d00d64df9 2020-12-05)

cargo install cargo-generate

cargo install cargo-generate

error: failed to run custom build command for openssl-sys v0.9.87 ... It looks like you're compiling on Linux and also targeting Linux. Currently this requires the pkg-config utility to find OpenSSL but unfortunately pkg-config could not be found. If you have OpenSSL installed you can likely fix this by installing pkg-config.

', /root/.cargo/registry/src/index.crates.io-6f17d22bba15001f/openssl-sys-0.9.87/build/find_normal.rs:190:5 note: run with RUST_BACKTRACE=1 environment variable to display a backtrace warning: build failed, waiting for other jobs to finish... error: failed to compile cargo-generate v0.18.3, intermediate artifacts can be found at /tmp/cargo-installguQK2f

TO FIX:

rm -rf /tmp/cargo-installcNl39M
apt install pkg-config
apt install libssl-dev

cargo install cargo-generate

This should (hopefully) be a temporary failure fixed in the cargo upstream (issue already closed).

Workaround:

cargo install cargo-generate --locked cargo

Failure and workaround described here: https://github.com/rust-lang/cargo/issues/9101
