So according to the Gospel of Spolsky 13:4, a core mission of Stack Exchange communities is to stop re-answering the same questions, and instead build a library of canonical answers. When general duplicates (instances of a problem) arise, we close and refer them to one such answer. For example:

bisig PPA causing 404 error? -> How can I fix a 404 Error when using a PPA or updating my package lists?

That said, many times on the review tab I see the same issues popping up, over and over... but don't know where to find the canonical question I know must exist! And should it not exist, that I know that we must make exist. Partial Upgrade errors anyone?


Please list common canonical questions that you know of in the following format. You can also answer with canonical questions you think should exist.

Is Jorge Castro a Robot?

Examples: How does Jorge Castro have so many badges?, I shook hands with a guy at UDS. Why was his hand cold and rubbery?, whiprush on internet - biology uncertainty

Queries: [if any, list data.stackexchange.com duplicate searches here]

Template:

### QUESTION_URL_HERE

**Examples:** DUPLICATE_URL_HERE, DUPLICATE_URL_HERE [and so on]

**Queries:** DATA_QUERY_HERE [omit this line if no query exists]

    I could see this page quickly growing out of control. There has to be a better way to maintain this information — dare I suggest a meta tag? – ændrük May 13 '12 at 20:16
  • I assumed moderators had a list somewhere that they passed around for such things. Is this not so? Is this question on meta meant to create such a list? – Chan-Ho Suh May 18 '12 at 1:20

    @Chan-HoSuh As I explained on chat, this is the canonical list. mods (like normal users) can (and do) maintain a personal list, but it's generally very specific. – jrg May 18 '12 at 1:48
  • I added a proposed bracket. I think desired, proposed, and accepted should all have lists. – RobotHumans Jun 15 '12 at 4:09
  • Dare I suggest to categorize the proposed questions (as they have done in TEX.SX), and not to restrict the list to "how to"s? I think it would be useful to have also readily available links to things like "What is a PPA?" and such. – carnendil Jan 18 '16 at 6:56

Existing canonical questions:












Desired canonical questions:


  • How do I diagnose fan problems?

    Possibly multiplexes into other questions for specific, common hardware configurations.


  • How to fix partial upgrades error?

    Common, fairly annoying.




  • Installing Ubuntu failed. What should I do?

    Countless examples


  • How do I swap / remap keys ?

    A variety of cases. Sytem-wide versus application-specific. Swapping keys or altering the layout in some way. Solutions also differ. There are DE-specific solutions and general X-windows solutions. Sometimes these conflict, causing their own issues.


  • The system has frozen up, although the mouse still works. What should I do ?

    Pointless to just tell them to file a bug, because ubuntu-bug alone doesn't capture the right information. There are specific troubleshooting steps to do in order to collect the required information, but what to do is also driver-specific. The Ubuntu-X freeze troubleshooting guide in wiki is a good reference but users often need some additional hand-holding and encouragement.


  • The session terminated and left me at the login screen. What do I do ?

    Basically need a full backtrace collected via gdb; apport is supposed to collect this but in cases where it's come to a question, it probably has failed to do so. The Ubuntu-X Backtrace wiki page walks the user through how to do this manually, but can be intimidating for less technically oriented folks.


  • My screen went blank and I can't turn it back on. What do I do ?

    The symptoms for "black screen bugs" are always indistinguishably similar, but the underlying causes are quite varied. There's several dozen different distinct causes for blank screens, and it's worthless to guess based merely on reported symptoms. But simply filing a bug report is not usually enough either, since you need to look at the status of things both before and after to spot differences. The Ubuntu-X wiki pages have some guides on what to do here, but most users need extra hand-holding.


  • How do I tell the difference between a hardware fault and a software bug ?

    Memory issues, overloaded power supplies, short-circuited motherboards, and loose wiring. Oh my!


  • I upgraded and something stopped working right. How do I narrow down what exactly broke?

    Package bisection search time. /var/log/dpkg.log to the rescue!

    What about my "How to port Ubuntu Touch to xyz device?" question - do you want that in this list? – Nathan Osman Nov 10 '13 at 21:00

I added a proposed bracket. I think desired, proposed, and accepted should all have lists.

Proposed

Example suitable duplicate: How to deal with a frozen screen?
Proposed canonical answer: What should I do when Ubuntu freezes?

Rationale: Different than, How do I file a bug?, How do I troubleshoot what is crashing?, and their ilk, but has a good detailed answer.

If we're in dupe or merge mode, this should probably be incorporated: Finding questions that other questions have been closed as a dupe of

Just saying, a list question that is unmaintainable is not a script that is maintainable.

Just thinking, do we have a Canonical answer for how to safely remove Ubuntu from a Double/Multi-boot? That would be useful I believe.

  • There likely already exists a answer along the lines of "boot off live CD, delete ubuntu partition, and reformat, or re-size the windows partition to over take the space." – virtualxtc Jan 15 '14 at 10:12
