    The problem

We have Ubuntu 22.04 / 20.04 VPS on OpenVZ and trying install WireGuard like this:
# curl -O https://raw.githubusercontent.com/angristan/wireguard-install/master/wireguard-install.sh
# bash ./wireguard-install.sh
OpenVZ is not supported
The solution

# apt install curl cargo
# cargo install boringtun
    Updating crates.io index
  Downloaded boringtun v0.6.0
  Downloaded 1 crate (59.6 KB) in 0.57s
error: there is nothing to install in `boringtun v0.6.0`, because it has no binaries
`cargo install` is only for installing programs, and can't be used with libraries.
To use a library crate, add it as a dependency to a Cargo project with `cargo add`.
# echo "fix boringtun v0.6.0 error"
# cargo install boringtun@0.4.0
# echo "continue..."
# ln ~/.cargo/bin/boringtun /usr/local/bin/
# curl -O https://raw.githubusercontent.com/angristan/wireguard-install/master/wireguard-install.sh
# sed -i 's/^\tcheckVirt/#\tcheckVirt/' wireguard-install.sh
# bash ./wireguard-install.sh
# sed -i '19 i Environment=WG_QUICK_USERSPACE_IMPLEMENTATION=boringtun' /lib/systemd/system/wg-quick@.service
# sed -i '20 i Environment=WG_SUDO=1' /lib/systemd/system/wg-quick@.service
# systemctl stop wg-quick@wg0
Warning: The unit file, source configuration file or drop-ins of wg-quick@wg0.service changed on disk. Run 'systemctl daemon-reload' to reload units.
# echo "fix wg-quick warning"
# systemctl daemon-reload
# echo "continue..."
# systemctl stop wg-quick@wg0
# systemctl start wg-quick@wg0
# systemctl status wg-quick@wg0
Done 🚀
