afiak the 32 bit libs error only happens when you try to install steam on a fresh ubuntu install without running ubuntu's update-manager beforehand.
I had the opposite problem, it didn't work on the fully updated Ubuntu (indeed the support page says it breaks with .04). The Valve instructions for Ubuntu only said to install all the available updates first so I made sure that was the first thing I did after installing the OS (would have been foolish to do otherwise even if the instructions didn't explicitly mention that due to how most linux distros manage their libraries). I tried installing Steam when linux was fully updated, first I tried installing it from the link the Valve Wiki had (the .deb file that unfortunately is 32bit only) then from the store where it didn't work either.
Unfortunately that's how distros work. There was a problem with Fedora 15 or 16 I think where the release .iso version couldn't be put onto a USB stick and was discovered a day or so after release. Even though it was a simple fix (rebuild with a newer version of something), they didn't update the .iso. Instead you had to follow directions to build your own .iso with the updated package, and then it would work.
It might have been much more than 3 lines of code to fix it though, so it might have taken more time (and needed through testing), or just hold off on the fixes until 13.04.
Website note though should have been done.
Indeed it would have been perfectly acceptable if they didn't update the installer and just put a warning that explicitly said that Wubi didn't work on Windows 8. The warning on the page is regarding UEFI hence it says to download x64 Ubuntu, had it not been about UEFI it would have said to simply download standalone Ubuntu so it's actually a confusing mess.
And again I repeat
Ubuntu 12.10 was released BEFORE Windows 8. The only double standards are coming from you and the fact that you feel compelled to blame others for the fact that Microsoft cannot write their bootloaders to interact properly with other operating systems. Your attempt to use a feature in an unsupported way is your fault not theirs. If Ubuntu could have done it during their testing phase, why couldn't Microsoft as well? You can guarantee that Ubuntu will probably work properly with the next release alongside Windows 8, but Microsoft will never fix the way their bootloaders break Linux.
No, it's only you that have double standards and keep mentioning the Windows 8 bootloader that nobody talked about and has nothing to do with this discussion. I used a Windows Ubuntu installer, shouldn't it support... I don't know... WINDOWS? If it doesn't support it and the company didn't bother updating it or putting a proper warning on the application or the page rather than one is that is related to UEFI whose fault is it? Who cares if according to their update schedule they update it every 6 months they could have made an exception and do something about it. It's like if after a car ran over you the driver would just came out with "SORRY, I ONLY BRAKE ON TUESDAYS". What kind of argument is that?
The install page simply says "Windows 8 or UEFI": http://www.ubuntu.co...tu-with-windows
Point is, Wubi is terrible and always has been. IMO it's only given people a bad taste of running Linux on Windows PCs.
The download page
has a different banner that says Windows 8 logo PCs and UEFI. The banners in both pages point to the UEFI page. Also is everybody sure that Wubi doesn't work on Windows 8 at all? After turning off hybrid boot it actually worked since Ubuntu booted properly (there are several blog/forum pages around that say that Wubi actually works on Win8 if you disable the hybrid boot), it was the install process afterwards that failed
