According to the Top 7, we need to select a 404 image - an image that will be displayed when users try to bring up a page that does not exist.

Please quote the source so the team can negotiate rights if necessary.

  • My comment applies to nearly all the answers below: The 404 image chosen should not be completely confusing to beginners. (The Tux one is pretty funny and not confusing; the "kernel panic" text ideas would be confusing and potentially worrying.)

we could create a black image showing the error message in kernelpanic-flavor.

like http://orionida.files.wordpress.com/2008/02/kernel-panic.jpg but with some other data and errors (404 should be shown somewhere)

    Save on bandwidth... we could just do this in html... and it'd still be funny Sep 17, 2010 at 5:01
  • let's put some html5 non compatible with ie8/7/6 and some SVG so we can lough at windowsians who still uses XP. Mouhahahahahahahaha

    Oh the irony -- your suggested image link is returning a 404.

It's not complete(as in, 25 rows of text) but maybe this is a start?

Server panic - Aiee, your file was not found!

I made it community wiki, so edit this to be more complete, then just put it on your favorite terminal and screen shot it (or if you want to be really awesome, recompile linux and put in these functions and make the linux kernel actually say this, and then screen shot it)

    Hmmm... a great idea for sure... I'm not very good at writing kernel modules, though. Dec 20, 2010 at 6:42

We couldn't find the page you were looking for...

Looks like Tux tried the rm -rf / command again. We really need to take that computer away from him.

Tux gets carried away.

Xeno found an image that I think could be a decent 404 picture, although we probably need to add text somewhere:

Proposed 404 image

We've got a couple other versions here and here

    I like the version here: i.imgur.com/uVOQS.png I think it makes no sense to include the java mascot Duke here ;-)

    @echox Yeah, I like that one the most too, although the editing was rather poor and should probably be redone if we actually use this for something Sep 12, 2010 at 23:58
cat: /foo/bar: No such file or directory

Maybe not cat, but how about GET:

HTTP GET: http://unix.stackexchange.com/foo/bar: No such file or directory

(Does it really have to be an image?)


useless use of cat

(from GirlieMac's HTTP Status Cats)


How about this as a U&L 404 "image" ? I tried to simulate loading (mounting) a URL, then a have a generalized fsck error message related to failing to find a URL.

# mount /http/URL /dev/console
mount: special device /http/URL does not exist
# fsck /http/url
fsck 1.43.1 (29-Jun-2016)
fsck: No such file or directory while trying to open /http/url

The superblock could not be read or does not describe a correct
URL. If the device is valid and it really contains a URL (and
not swap or ufs or something else), then the superblock is 
corrupt, and you might try running fsck with an alternate superblock.

You are now being dropped into an emergency shell.
