Ubuntu 12.04 LTS available today

[D. Hugh Redelmeier]

I've just downloaded the new Precise Pangolin i386 .iso.

As usual, they make it awkward to authenticate: the checksums are not 
clear from the download page.

If you go to an FTP directory (say ftp://ftp.telus.net/pub/ubuntu/12.04/), 
you will see checksums.

I've not bothered to find an authoritative place to find the release's GPG 
key.  When I do check the checksums, GPG whines in a way that I don't 
completely understand:

    [hugh at redsquare ubuntu-12.04]$ gpg --verify SHA256SUMS.gpg SHA256SUMS
    gpg: Signature made Thu 26 Apr 2012 05:54:04 AM EDT using DSA key ID FBB75451
    gpg: checking the trustdb
    gpg: public key A3D025C7 is 383 seconds newer than the signature
    gpg: public key 970F6D91 is 1084 seconds newer than the signature
    gpg: public key FBBB8AB1 is 58138 seconds newer than the signature
    gpg: 3 marginal(s) needed, 1 complete(s) needed, PGP trust model
    gpg: depth: 0  valid:   1  signed:   0  trust: 0-, 0q, 0n, 0m, 0f, 1u
    gpg: Good signature from "Ubuntu CD Image Automatic Signing Key <cdimage-GeWIH/nMZzLQT0dZR+AlfA at public.gmane.org>"
    gpg: WARNING: This key is not certified with a trusted signature!
    gpg:          There is no indication that the signature belongs to the owner.
    Primary key fingerprint: C598 6B4F 1257 FFA8 6632  CBA7 4618 1433 FBB7 5451

It seems odd that a key would be newer than a signature (on it?  using
it?  The message isn't clear).

There are links from
<http://www.ubuntu.com/download/desktop/alternative-downloads> to DVD
images.  With the additional space comes some additional stuff:

    For a copy of Ubuntu that includes all the language packs and some
    other useful applications, such as Inkscape, GIMP, Pitivi, plus a more
    complete LibreOffice suite, click on your nearest mirror from the list
    below, then navigate to the DVD folder. Do note that these images are
    too big to fit on CDs.

    If you don't need the full language pack, we recommend the
    standard CD installer as all other packages are available in the
    Software Centre.

I think that I'd like the DVD image -- the other applications do seem
useful.  But perhaps that is just greed:  many packages get updated
from the internet anyway so the DVD version becomes useless.

Unfortunately, I get a 404 when I try to download from the US mirror,
the place that that page points us to.

I have no immediate plans to install 12.04 i386, but I am using its 
memtest86+ to test some RAM I picked up yesterday.  I use AMD64 versions 
where possible; none of those systems have CD drives that are not also 
DVD drives so I'm waiting for the DVD .iso.
