Bug Description

I am deploying a bundle with a cloud-init script and occasionally the cloud-init aborts due to transient failures in charm download. For example:

Executing changes:
- upload charm alertmanager-k8s from charm-hub from channel edge with architecture=amd64
ERROR cannot deploy bundle: cannot add charm "alertmanager-k8s": downloading charm "ch:amd64/focal/alertmanager-k8s-53" from origin {charm-hub charm 0xc001de28e8 edge amd64/ubuntu/focal }: cannot retrieve "https://api.charmhub.io/api/v1/charms/download/07j6JDIq52o1PstlKtrrpDLxAq4mPU5P_53.charm": cannot get archive: Get "https://canonical-bos01.cdn.snapcraftcontent.com/download-origin/canonical-lgw01/07j6JDIq52o1PstlKtrrpDLxAq4mPU5P_53.charm?token=1675814400_d06c69884b0a3e13678b0cdaa3d06ab9306e0917": read tcp 10.1.79.200:37160->91.189.91.42:443: read: connection reset by peer

I wonder if there's already an auto-retry in place, and if not then should it be added?

We have some plans for refactoring part of the charm/bundle deployment process. These changes will address this problem. Unfortunately, this will not be done in the short term.

Thanks for reporting.

This isn't "Won't Fix"; it's something we should and will deal with. In a distributed environment, Juju should be resilient to transient failures. That behaviour is baked into various cloud SDKs already (so we get it for free). But we need to plug gaps in other areas as well.
