After searching http://askubuntu.com I was looking through all the unanswered questions and its frustrating trawling through 607 unanswered questions at 15 per page (approx 9,105) and it appears that questions remain unanswered for the following reasons (with links to a few examples of each type, to demonstrate):
- Question answered by a comment - and accepted by person who posted the question, but they never bother to change it into an answer. It appears that the site admin doesn't sort them out either, as they are left in lmbo for years, (e.g.):
Ubuntu 18.04 logs out unexpectedly or crashes
failed to enroll MOK key on upgrade 17.10 -> 18.04
How to change Nautilus shortcuts keys in Ubuntu 18.04?
- Question is regarded as too broad - however it is not flagged as such; it's just a comment again, and the latter recommended it should go to chat. It appears that's what happened, but the question is still flagged as unanswered:
Why do keyboard shortcuts stop working in Ubuntu 18.04 with Gnome.
gnome-terminal hides ending characters of the current path's first row
- Question is awaiting feedback - Questions are still awaiting feedback over a year:
Window manager warning: Overwriting existing binding of keysym XXX with keysym XXX (keycode XX)
vboxdrv does not exist. after kernel installation
- Question is literally unanswered - for example:
Use Bluetooth headset with microphone (HFP) in Ubuntu 18.04
PlayOnLinux not detecting FreeType fonts - ubuntu 18.04
VPN disconnect - do not stop internet
Answered but answer not yet accepted - of which at time of writing there are:
9,099 questions with no upvoted or accepted answers, despite a lot of them are actually answered but not yet accepted.
Very high Xorg memory usage with Ubuntu 18.04
What causes "PKCS#7 signature not signed with a trusted key"
IMHO, I think these could be dealt with as follows:
(1) No one should answer a question with a comment, but it appears to be common. In many cases, the person asking the question has even accepted the answer. Suggest that when entering a comment you should get a warning to make it clear you should not use comments to answer and what is it now? +50 to comment? Suggest it should be much higher and then it should be only the sort of people will never answer with a comment; maybe add an incentive by means of a points deduction, to put people off the malpractice and add this to the warning every time someone goes to add a comment. Also, housekeeping should sort out ones that have already been answered by a comment and prompt the person who answered to post it as an actual answer, and the person who asked the question to accept the answer.
(2) If a question is regarded as too-broad or for any other reason is not accepted, then it should be flagged in some way and deleted after n days/n months.
(3) If a question doesn't get feedback from the person who asked the question after say 1 month, then delete it.
(4) What you do about questions still unanswered? I don't know, but if I asked a question and it was unanswered for over a month it is highly likely I have since found a solution by then, and would answer it myself allowing it to be closed off at some point, but many users, especially new ones, do nothing. Suggest you email the person to tell them the question is about to be closed if you get no feedback, then delete the question.
(5) Suggest administrators or those whose task it is, to make a point of going through questions and prompting the the person asking the question to mark the answer as accepted or whatever you can do to arrive more quickly at an accepted answer. for example this question is over 7 years old, it has 6 answers, the last has the most votes with 1131, so why didn't/doesn't someone simply mark that as the accepted answer since its clearly the best answer and why is it not right at the top since it has the most votes?:
How can I copy the contents of a folder to another folder in a different directory using terminal?
Also if you are looking only for an answer there is no option to list only answered questions or answered questions that actually have an accepted answer! suggest you add an Answered option to the list or
Answered (not accepted):
