I wonder if this is a bug in juju metadata. I noticed recently that when I generate data for tools , 1.15.0 is always the version for amd64. I think the version is selected from the oldest tool found for the series+arch.

Metadata might be unrelated. Juju is trying to be smarter about selecting sane archs for clouds. Previously it assumed the remote arch was the same as the local arch. I don't see much evidence of i386 being a sane selection for a cloud. The primary use of juju i386 is to provide a client that can work with amd64 clouds.

I would target this to a 1.18.2 if it existed.
This is a change in behavior from 1.16 to 1.18. If you just do:
 juju-1.18 bootstrap -e amazon
I end up getting a i386 target. I have to do:
 juju-1.18 bootstrap -e amazon --constraints="arch=amd64"
for it to pick a amd64 (which was always the default in 1.16).
I would probably expect the tool to default to its own architecture (so if deploying from an amd64 prefer an amd64, etc).

I have created a 1.18.2 milestone. I cannot reproduce this behaviour. I don't see CI doing it as well.

I just saw this happen testing 1.19.0 deployment on aws fom my amd64 machine.
