安装Using Free VPN Service on Linux - RiseUpVPN

From https://riseup.net/en/vpn: Riseup offers Personal VPN service for censorship circumvention, location anonymization and traffic encryption. To make this possible, it sends all your internet traffic through an encrypted connection to riseup.net, where it then goes out onto the public internet. Unlike most other VPN providers, Riseup does not log your IP address.
