License: switch fleet info.xml from `agpl` workaround to `EUPL-1.2` once NC 34 is the floor

[rubenvdlinde]

Background

All Conduction Nextcloud apps are licensed EUPL-1.2 (canonical, see project_conduction-apps-eupl-license). For years the Nextcloud appstore rejected <licence>EUPL-1.2</licence> in info.xml because it wasn't on the SPDX allow-list — so the fleet uses <licence>agpl</licence> as a workaround (EUPL-1.2 is AGPL-3.0 compatible per its compatibility appendix, so this is legally honest, just lexically wrong).

Ruben raised this upstream a while back. It's now fixed, but ship-timing means the workaround stays for a bit.

Upstream status

Item	State	Notes
nextcloud/appstore#1710 — "Add EUPL-1.2 to accepted licence identifiers"	CLOSED / COMPLETED (2026-05-07)	Original tracking issue
nextcloud/appstore#1754 — "Add further compatible app licenses"	MERGED (2026-05-07)	Appstore-side: deployed to apps.nextcloud.com
nextcloud/server#60212 — "feat(app-licenses): Add further compatible licenses for apps to use"	MERGED (2026-05-11) into master	Server-side validation; ships in Nextcloud 34

Implication for our fleet

• Right now: the appstore-side accepts EUPL-1.2 uploads, but apps installed on Nextcloud 33 or older would see info.xml validation errors locally (server still on the old allow-list). Keep agpl until our info.xml <nextcloud min-version="34">.
• When the fleet min-version reaches 34: flip every app's <licence>agpl</licence> → <licence>EUPL-1.2</licence>. This will also fix the casing-drift the fleet currently has (agpl / eupl / EUPL-1.2 / AGPL-3.0-or-later — 4 spellings across 22 apps; see nextcloud-app-template/docs/fleet-drift-deeper.md).

Current fleet min-versions (NC)

From the fleet-drift-deeper.md audit:

• min-28 (most of the fleet)
• min-29 (mydash)
• min-30 (docudesk, openklant, opentalk, openzaak, valtimo)
• min-31 (app-versions)
• min-33 (scholiq)

So we're still far from min-34 fleet-wide. This issue is not actionable today; it's a tracker for when the floor rises.

Action items

1. Track NC release adoption. Once the fleet's info.xml min-version is universally 34+, this issue becomes actionable.
2. When ready: include the <licence> flip in the info.xml canonicalization sweep planned in fleet-drift-deeper.md Tier A item 1. The hydra fleet-sync tool can carry the change.

Until then

Keep using <licence>agpl</licence> in appinfo/info.xml and document the workaround in each app's README.md (already standard per the project-memory entry). Don't flag the AGPL/EUPL discrepancy as a bug — it's the deliberate workaround.
