I use Ubuntu for my workstation and administer a lot of Debian servers. In my experience 98% of the times an Ubuntu solution applies on Debian at a similar age and vice versa.
Recently when searching Google for an issue I had on a Debian server, I noticed an Ubuntu answer that doesn't work, so I worked out the solution on my own. I was about to add that as an answer on the question, but somehow decided to come here first. I saw this question When are Debian questions off topic? but it's about questions, not answers.
Is it appropriate to add a Debian answer (for Jessie and later) here that doesn't work on Ubuntu (package name and functionality is different), where an existing answer is valid for Ubuntu Precise and later?
I personally think Debian has a special scope here because Ubuntu is derived from Debian, while distros like Mint or Kali generally don't have any influence on Ubuntu.
