Adds Ubuntu 26.04 (resolute) as a supported OS across Vito and every server provider, fixes what breaks when provisioning it, and makes Proxmox template setup easier. Supersedes #1081.

Ubuntu 26.04

  • OS: ubuntu_26 / 26.04 is selectable in the UI, API and workflows.
  • Providers: Hetzner (ubuntu-26.04) and Linode (linode/ubuntu26.04) got image entries. DigitalOcean, Vultr and AWS already look images up by version, and all publish 26.04 images. Proxmox gets an "Ubuntu 26.04 Template" field. Custom needs nothing.
  • Provisioning fixes needed on 26.04:
    • PHP: installs from packages.sury.org. The ondrej PPA has no 26.04 builds and its description points to sury for resolute. Older releases keep the PPA.
    • mise: the apt key is stored dearmored as .gpg. APT 3.x's sqv verifier rejects an armored key saved as .pub (the fix from [Feat] Add Ubuntu 26 support #1081).
    • MariaDB: the repo setup skips MaxScale, which has no 26.04 repo and would break every later apt-get update, and fails loudly if setup fails. 10.11 and 11.4 aren't published for 26.04, so they're rejected with a 422 on server create and service install (new RegisterServiceType::unavailableVersions() and ServiceVersionAvailableRule).
  • Checked against the live repos: MySQL 8.4/9.7, PGDG 15–18, GoAccess, Caddy and NodeSource all publish for resolute, and every third-party signing key passes APT 3.2's Sequoia policy.

Proxmox

  • Setup guides: each Ubuntu template field has a guide button inside the input. It opens copyable steps for that version: download the cloud image, add the guest agent, build the template with a suggested VM ID, check it with qm config. Any input can use this via DynamicField::withGuide(). The top-level guide now covers the API token and connecting.
  • Editable template VM IDs: the edit dialog shows the template fields prefilled.
    • Changes are merged into the stored credentials on the server, so the token secret never reaches the browser.
    • Templates are re-verified against Proxmox only when a VM ID changes, so a rename never calls Proxmox.
    • The API update endpoint accepts the same fields.
  • Plugin-safe: the edit methods live in a new opt-in HasEditableCredentials interface that only Proxmox implements. The ServerProvider contract is unchanged.
  • Access: editable_data is only returned to callers who can update the connection and, for API tokens, have the write ability (revealCredentials, as for storage providers). Broadcasts never include it.
  • Dialogs: a new openNested() in the dialog store lets the guide open on top of the edit dialog without discarding unsaved input.

Testing

  • Full suite passes (2397 tests), plus PHPStan, tsc, eslint and pint --test.
  • Tested manually with the Proxmox provider on Ubuntu 26.04.

Follow-ups (not in this PR)

  • Sury's signing key expires 2028-02-04 and is only re-fetched when a PHP version is installed.
  • Moving existing 22.04/24.04 servers from the PPA to sury, and installing Vito itself on a 26.04 host.

Summary by CodeRabbit

  • New Features
    • Added Ubuntu 26.04 support for server creation, provider images and Proxmox templates.
    • Proxmox template IDs can now be edited after connection, with validation before changes are saved.
    • Setup guides can open in a nested dialog, keeping the current dialog available.
  • Bug Fixes
    • PHP installation now selects the appropriate package source for Ubuntu 26.04.
    • MariaDB 10.11 and 11.4 are unavailable on Ubuntu 26.04; other supported versions remain available.
    • Improved MariaDB repository setup and Mise signing-key installation.

Add Ubuntu 26.04 (resolute) as a supported OS across the app and every
server provider, and fix what breaks when provisioning it.

- OperatingSystem::UBUNTU26 and core.operating_systems; Hetzner and Linode
  image maps; DigitalOcean, Vultr and AWS already resolve images by version.
- Proxmox gets an Ubuntu 26.04 template field (template fields now a 2x2 grid).
- PHP: 26.04 installs from packages.sury.org (the ondrej PPA has no 26.04
  builds); older releases keep the PPA.
- mise: store the apt key dearmored, since APT 3.x rejects an armored .pub key.
- MariaDB: skip the MaxScale repo (404 on 26.04) and fail loudly if repo setup
  fails; reject 10.11/11.4 on 26.04 via RegisterServiceType::unavailableVersions()
  and ServiceVersionAvailableRule on server create and service install.
- Docs and OpenAPI updated; tests added.
- Each Ubuntu template VMID field (connect and edit forms) has a guide button
  inside the input that opens copyable, version-specific steps: download the
  cloud image, add the QEMU guest agent, build the template with a suggested
  VM ID and check it. DynamicField::withGuide() attaches such a guide to any
  input; the top-level Proxmox guide keeps the API token and connect steps.
- Proxmox connections can be edited: the edit dialog shows the template VM IDs
  prefilled. Changes are merged into the stored credentials server-side (the
  token secret never reaches the browser) and templates are re-verified
  against Proxmox only when a VM ID changes. Errors for fields the form doesn't
  render are reported on provider. The API update endpoint accepts the same
  fields.
- New opt-in HasEditableCredentials interface (only Proxmox implements it), so
  the ServerProvider contract and existing plugins are unchanged.
- editable_data is revealed only to callers who can update the connection and,
  for API tokens, carry the write ability (revealCredentials, as for storage
  providers); broadcasts never include it.
- The dialog store gains openNested(), so a guide opens on top of the edit
  dialog without discarding unsaved input.
- Docs, OpenAPI and tests updated.

📝 Walkthrough

Walkthrough

This change adds Ubuntu 26.04 support, operating-system-specific service version restrictions, and operating-system-dependent PHP repository selection. It also adds editable Proxmox template credentials, provider-specific edit forms, and nested dialogs for dynamic-field setup guides.

Changes

Ubuntu 26.04 support

Layer / File(s) Summary
Ubuntu 26.04 server provisioning
app/Enums/OperatingSystem.php, config/core.php, config/serverproviders.php, docs/4.x/servers/create.md, public/api-docs/openapi/schemas/Server.yaml, public/api-docs/openapi/servers.yaml, tests/Feature/ServerTest.php
Ubuntu 26.04 is included in the operating-system enum, configuration, provider image mappings, API descriptions, and server-creation tests.
OS-specific service version validation
app/Plugins/RegisterServiceType.php, app/ValidationRules/ServiceVersionAvailableRule.php, app/Actions/Server/CreateServer.php, app/Actions/Service/Install.php, app/Providers/ServiceTypeServiceProvider.php, resources/views/ssh/services/database/mariadb/install.blade.php, docs/4.x/plugins.md, docs/4.x/servers/database.md, public/api-docs/openapi/servers.yaml, tests/Feature/ServerTest.php, tests/Feature/ServicesTest.php
Service types can declare versions unavailable for an operating system. Validation checks server creation and service installation. MariaDB 10.11 and 11.4 are marked unavailable on Ubuntu 26.
PHP and Mise repository setup
app/Services/PHP/PHP.php, resources/views/ssh/services/php/install-php.blade.php, resources/views/ssh/mise/ensure-installed.blade.php, resources/views/ssh/os/install-dependencies.blade.php, docs/4.x/servers/php.md, tests/Feature/PHPTest.php, tests/Feature/ServerTest.php
PHP installation selects a repository based on the operating-system version. Mise setup installs GnuPG and uses a dearmoured keyring.

Editable provider credentials

Layer / File(s) Summary
Editable credential contract and access
app/ServerProviders/HasEditableCredentials.php, app/Plugins/RegisterServerProvider.php, app/Policies/ServerProviderPolicy.php, app/Models/ServerProvider.php, app/Http/Resources/ServerProviderResource.php, app/Tables/ServerProviderTable.php, resources/js/types/*, public/api-docs/openapi/schemas/ServerProvider.yaml, tests/Feature/ServerProvidersTest.php
Providers can opt in to editable credentials and define edit forms. Provider responses include editable data when the user has permission. Unregistered providers return empty editable data.
Proxmox template editing and verification
app/ServerProviders/Proxmox.php, app/Providers/ServerProviderServiceProvider.php, app/Actions/ServerProvider/EditServerProvider.php, docs/4.x/plugins.md, docs/4.x/settings/server-providers.md, public/api-docs/openapi/server-providers.yaml, public/api-docs/openapi/user-server-providers.yaml, tests/Feature/ProxmoxProviderTest.php
Proxmox exposes Ubuntu template VMIDs as editable fields and generates operating-system-specific setup guides. Changed credentials are connected and verified before assignment. API descriptions and tests cover template updates, validation errors, and credential visibility.
Edit forms and nested setup guides
app/DTOs/DynamicField.php, resources/js/stores/dialog-store.ts, resources/js/components/dialogs/dialog-host.tsx, resources/js/hooks/use-dialog.ts, resources/js/components/ui/dynamic-field.tsx, resources/js/pages/server-providers/components/edit-dialog.tsx, resources/js/pages/server-providers/index.tsx, .github/instructions/frontend.instructions.md
The dialog store and host render active and nested dialogs. Provider edit forms render configured dynamic fields, and fields with setup guides can open a nested dialog.

Merge Risk: 🔵 Low · up to 5f472

Ubuntu 26.04 support and editable Proxmox templates look mergeable. One small risk remains: on servers whose login shell lacks pipefail support, a failed Mise key download may not stop setup early.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to 5f472

Credential edits remain restricted to authorized users and are verified before saving. However, simultaneous edits can silently undo an accepted template change, affecting which image a later server uses.

Retained concerns

  • Medium · reliability · inferred: Concurrent authorized template edits can each pass verification, but the later whole-credential save can discard the earlier accepted mapping. Subsequent provisioning may clone the older mapped image.
Security review details

Security Blast Radius

  • inferred — The observed new reachability is confined to callers authorized to edit a provider record, but that record's mappings determine template selection for later servers provisioned through the connection. The Proxmox token's external permissions were not established.

Security Findings and Attack Paths

  • inferred — The supported failure path is an authorized concurrent-edit race, not a demonstrated unauthorized credential edit or secret disclosure. An overwritten mapping can cause later provisioning to use a template other than the one from an accepted edit.

Trust Boundaries and Controls

  • observed — The policy requires ownership and project write authority for updates. Submitted edit fields alter template mappings rather than the stored token; verification uses that token server-side and checks template visibility, type, and cloud-init configuration.

Resilience and Maintainability Implications

  • inferred — The Mise key-download pipeline already existed on the target branch. The new attempt to enable pipefail depends on the remote account's shell, which the SSH executor does not select for these calls; this is an unresolved protection limitation, not evidence that this PR introduced a new download-failure path.

Hardening Proposals

  • proposed — Use a credential-record version check or another serialized update strategy so a conflicting edit must re-merge and re-verify against the latest stored mappings before it can succeed.

the exception and log a warning containing only non-sensitive metadata, such as
the provider identifier and exception class; do not log the exception message or
trace. Preserve the existing ValidationException 422 response.

Review comments at @resources/views/ssh/os/install-dependencies.blade.php:
- Line 7: Enable Bash pipefail for the Mise GPG-key setup scripts containing the
curl-to-gpg pipeline, including the pipeline before the mise.list write, so a
curl failure stops execution even if gpg succeeds.

- EditServerProvider::verify() logs the connection and exception class (never
  the message) before returning the generic 422, as EditStorageProvider does.
- The mise key scripts enable pipefail: gpg --dearmor exits 0 on truncated
  armor, so a download cut off mid-transfer used to leave a broken keyring and
  only fail later at apt-get update.
