Public bug reported:

In a ticket filed in the Ubuntu RT instance we were made aware of an
issue where if a cloud is configured with an “_” in the region name,
cloud-init will generate an apt configuration that also includes that
“_” in the name.

So for example if the region name is zone_01, apt will be configured to
use zone_01.clouds.archive.ubuntu.com.

On Friday March 13th we deployed some new archive servers on 18.04 using
Apache 2.4.29-1ubuntu4.13. This version of apache has more strict
protocol options than previous versions, per
https://httpd.apache.org/docs/2.4/mod/core.html#httpprotocoloptions and
the result is that a request to zone_01.clouds.archive.ubuntu.com
returns a 400 Bad Request.

Could cloud-init be updated to remove non-permitted characters including
“_” per https://tools.ietf.org/html/rfc3986#section-3.2.2 ?
