Disclaimer: The course seems to be written with something like a SaaS gitbook and the source is not public so I'll open an issue rather than a PR.

On page https://gosecure.github.io/xxe-workshop/#1, in the Interesting files to read section, it's recommended to read file:///proc/self/net/dev because Include public and internal IP but the architecture seems to have changed, now this file includes only received and transmitted packet counters for each interface but no IP information. /proc/self/net/if_inet6 contains all IPv6 interface IP. But there is no equivalent for IPv4. /proc/net/fib_trie list some IPv4 addresses but not associated to the interface.

You also mention file:///etc/lsb-release which is long deprecated an os-dependant. /etc/os-release replaces all /etc/debian_version, /etc/lsb-release, /etc/redhat-release, /etc/fedora-release, etc.
