All affects x86 version

[Dimitri John Ledkov (xnox)]

This looks like a regression since the 1024D keys were dropped from ubuntu-keyring.

Will make sure that only 4k key is used to sign the image.

Attaching tarbal of /var/log from lp:1638086

[Lyn Perrine (walterorlin)]

I get this with the lubuntu alternate install i386 images

[Jason Gerard DeRose (jderose)]

FYI, same thing is happening with the latest Zesty server ISO (see attached).

[Daniel van Vugt (vanvugt)]

Confirmed the same failure with both images: 20161030 and 20161031

Can I get a slightly older one from somewhere?

[Daniel van Vugt (vanvugt)]

Also, why are we replacing old daily images with new ones that don't install? Is there a gap in our testing?

[Dimitri John Ledkov (xnox)]

So Release.gpg file in the apt archive inside the .iso is currently signed using 1024D key only; instead of both; or just the 4k key.

[Dimitri John Ledkov (xnox)]

Fix deployed to the image building scripts. Ubuntu zesty amd64 respin looks good. Things should return to normal with next cronned builds; that is images with build stamps 20161102 and later should be all good.

[ernsteiswuerfel (erhard-f)]

Works for me (PowerBook G4 5,6, ppc).

[Daniel van Vugt (vanvugt)]

Yep, works now thanks. Just hitting other bugs. Business as usual.
