[Kea-users] Kea Cloudsmith packages for Ubuntu 26.04 built for x86-64-v3

[Braden Obrzut]

I'm not sure if this was intentional or not, but the Cloudsmith repo for 
Kea 3.2 contains binaries which nominally require a host that is 
x86-64-v3 (you can verify with readelf -n).

I did some tests and it appears if you opt into amd64v3 packages for 
Ubuntu 26.04 the build toolchain you receive will produce binaries that 
require x86-64-v3.  Changing -march would not be enough since the note 
that declares the requirement is part of crt1.o.  I'm not sure how the 
official packages are produced but if it's a Ubuntu 26.04 host 
environment opted into amd64v3 it would seem this requirement may have 
been introduced accidentally.

Alternatively if it is intentional, it would probably make sense to 
serve the packages as amd64v3 rather than amd64 if that's something 
Cloudsmith can do so they don't get accidentally installed on hosts with 
older CPUs.

The Ubuntu 24.04 repo seems to work fine on 26.04 so I'm able to use 
that as a work around.
