# Update Flake
|
|
|
|
## Workflow
|
|
|
|
### 1. Update All Inputs
|
|
|
|
The flake tracks `nixos-unstable`. Update everything at once:
|
|
|
|
```bash
|
|
nix flake update
|
|
```
|
|
|
|
### 2. Check for Breakage and Fix
|
|
|
|
Build errors typically fall into these categories:
|
|
|
|
- **Patches failing to apply**: Check `patches/` directory. Rebase or remove patches if the upstream issue was fixed.
|
|
- **Nextcloud version bump**: Check `common/server/nextcloud.nix` for the pinned version (e.g. `pkgs.nextcloud32`). If nixpkgs dropped the current version, upgrade by exactly ONE major version. Notify the user.
|
|
- **Removed/renamed packages or options**: Search nixpkgs history for migration guidance and apply fixes.
|
|
- **stateVersion changes**: If ANY change requires incrementing `system.stateVersion`, `home.stateVersion`, or data migration — STOP and ask the user. Do not proceed.
|
|
|
|
### 3. Build All Machines
|
|
|
|
See [references/machines.md](references/machines.md). Get machine list and build each:
|
|
|
|
```bash
|
|
nix eval .#nixosConfigurations --apply 'x: builtins.attrNames x' --json
|
|
nix build .#nixosConfigurations.<hostname>.config.system.build.toplevel --no-link
|
|
```
|
|
|
|
Fix any build failures before continuing.
|
|
|
|
### 4. Garbage Collection
|
|
|
|
```bash
|
|
nix store gc
|
|
```
|
|
|
|
### 5. Summary
|
|
|
|
Report: inputs updated, fixes applied, nextcloud changes, and anything needing user attention.
