You need to upgrade your libsodium version to match the requirement, which is version 1.0.13 or above.

Ubuntu:

$ sudo apt install php-libsodium

CentOS:

$ yum install php-pecl-libsodium2

Restart your web-server.

After installing libsodium, make sure that it is loaded:

$ php -i | grep libsodium
libsodium headers version => 1.0.17
libsodium library version => 1.0.17

If you get another error such as PHP Fatal error: sodium_init() in Unknown on line 0, you should try installing libsodium using PECL. But for now at least you should try installing it using apt/yum first.
