I have Ubuntu 22.04.1 LTS and often have issues with it, but can never find a relevant answer here. 10 year old answers just don't work for newer versions of Ubuntu.
First, I generally disagree with you that "all the questions/answers on this site so old" and that you "can never find a relevant answer here". That's an over-generalization that simply isn't true.
However, I can think of some examples where this can be true. Question and answers that are very specific to certain desktop environments can change dramatically over time. My advice here would be to first search for a relevant answer. If none is found for your particular version of Ubuntu, ask a new question, and tag it with your version (22.04 for instance). Then it's perfectly clear that the question and answer is for that particular version.
There are many topics where 10-20 year old answers are still perfectly valid. Some examples are:
- General Debian/Ubuntu package management (basic features of
apt- not newer features of course)
- Generel CLI applications - GNU coreutils,
- General scripting questions (Bash, Python etc. - basic features, not cutting edge)
- Kernel and application compilation questions
- Other questions on general Ubuntu and Linux topics
Then there are some questions, where you have to know when underlying technologies have changed. In these cases, only answers from after the Ubuntu version in which these features were introduced apply in that scenario. Again some examples:
systemdwas introduced (replacing
upstartas the default init system) in Ubuntu 15.04
netplanwas introduced (replacing
ifupdownfor network configuration) in Ubuntu 17.10
ZFSfilesystem support (kernel module) was added in Ubuntu 16.04
python2was removed from the distribution as default in Ubuntu 20.04
- PulseAudio was introduced in Ubuntu 8.04 - and again replaced by PipeWire in Ubuntu 22.10
- Wayland as a display server was included from Ubuntu 17.10 - and recently was changed to default for non-Nvidia cards on Ubuntu 21.04 and Nvidia cards on Ubuntu 21.10
- Gnome 3.X Desktop was introduced in Ubuntu 18.04 (default flavor)
- Gnome 4X Desktop was introduced in Ubuntu 21.10 (default flavor)
Just for reference, there are currently:
1,616 of those have answers
Another 3,458 that mention 22.04 but are missing that tag.
1,445 of those have answers
And that's 10 months into the 22.04 lifecycle.
Sure, there are hundreds of thousands more that apply to even older releases (or may not mention any release), but if you ...
can never find a relevant answer here
... then you are hitting some really bad odds ;-). But, as @ArturMeinild mentioned, if that's the case, then please do add your question! If there's already a question out there that doesn't have an answer (or that answer doesn't work for you) - Upvote and perhaps even add a bounty!
I have registered on this site in December 2020, and the focus of my interest was 20.04.
My main motivation in registering was to share solutions to stumbling blocks that I encountered, and to thus give back to the Ubuntu project (which I appreciate a lot). Helping others here seemed to be a good way to contribute. I ended up posting quite a few answers before posting my first question.
All the while, I did not find a usable answer to the most painful problem that I had with Ubuntu at the time.
I ended up having to research the topic myself with only the tiniest of assistance.
Six weeks later, AskUbuntu finally got equipped with a very detailed, very helpful answer regarding my original question. This answer had everything in it that I wished to find in the first place! Its appearance was not a coincidence however: having been succesful in my research and in reaching my goal, I posted it myself.
I share this story to illustrate how dedication produces the content on this site, and how it can sometimes be our own dedication that contributes to our collective success.
