I’ll just add some additional details, that I don’t know if is known or not…
- the current wiki we have may no longer exist in six months; with data being moved as was documented here and in a recent UWN (UWN link just gives a summary & sends you to first link anyway; what Ubuntu Weekly Notice does)
- due to expected retirement of current docs, I will suggest you explore newer options, esp. if you'd like to contribute more to documentation; alas that doesn't help current fix right now
The current page [code] you linked, I’ve posted at the pastebin Ubuntu Pastebin Whilst there is a ‘view raw’ option which should show this detail; I’m not sure if all options appear when you’re not a wiki-editor; which is why I’ve provided a pastebin of it.
That pastebin detail I hope is useful in indicating what change(s) you want to make.
Thank you for trying and offering to contribute, and making Ubuntu better.
