22.10 - Failed to build charm for bases index '0'.
Metadata
Current evaluation
Reporter's reactive charm failed to build; maintainer facundobatista closed it as not a Charmcraft bug — the legacy `charm` tool rejects metadata.yaml without a `series` list. Author agreed and took it to the Juju team.
Resolution: closed not a bug
Reason: Closed by maintainer facundobatista on 2022-06-27 with the diagnosis that the external `charm` build backend (used by reactive charms) errors with 'E: missing series: must be a list of series names', i.e. the upstream charm's metadata.yaml was the problem, not Charmcraft. The author confirmed on 2022-06-28 that the tested change dropped the series section and would follow up with the Juju team.

| #639 Can't build charm: Failed to build charm for bases index '0' | charmcraft | closed | Closed as a dependency/configuration issue: adding setuptools fixed Jinja2 packing, while Tempita required setuptools <58. A later build recovered after charmcraft clean. | |
| #529 Charm deployment to OSM fails | charmcraft | closed | Maintainer facundobatista closed it as not charmcraft-related: bundle.yaml pointed at a build directory, not the generated powerdns.charm. Reporter confirmed deploying works after using the .charm file path. | |
| #904 Can't build/pack a charm with Focal | charmcraft | closed | Closed as an upstream charm-tools bug; the missing MarkupSafe failure was tracked in juju/charm-tools#646. | |

| #632 Cant build charm with charmhelpers - missing markupsafe | charmcraft | closed | Charmhelpers-based charm build failed with missing markupsafe via Jinja2/setuptools 58+ vs Tempita 2to3 conflict. cmatsuoka diagnosed it and the reporter confirmed the workaround works; maintainer closed the issue as solved without a charmcraft code change. | |
