# cachy-auto-update
|
|
|
|
Unattended background updates for CachyOS (supports pacman, AUR, Flatpak and AppImages).
|
|
|
|
Built for the machine you set up for somebody else and would rather not maintain.
|
|
Stays out of the way while they are gaming or on battery, never touches the
|
|
package database while `pacman` is already running, and only bothers you if something
|
|
went wrong.
|
|
|
|
## Install
|
|
|
|
```bash
|
|
paru -S cachy-auto-update
|
|
sudo cachy-auto-update enable
|
|
```
|
|
|
|
Updates are **off** until you enable them.
|
|
|
|
## Usage
|
|
|
|
```bash
|
|
sudo cachy-auto-update
|
|
```
|
|
|
|
```

Everything is configurable from **[6] Settings**.
|
|
The interface is also translated to German (more langs coming soon (maybe)).
|
|
|
|
## What it updates
|
|
|
|
| | |
|
|
|---|---|
|
|
| Repository packages | `pacman -Syu` |
|
|
| AUR | `paru` or `yay`, whichever is installed |
|
|
| Flatpak | system and per-user installations |
|
|
| AppImages | via [Gear Lever](https://github.com/mijorus/gearlever), if installed |
|
|
|
|
|
|
## When it doesn't update
|
|
|
|
A run is postponed (retried an hour later) when:
|
|
|
|
- battery is below 30 % (ignored on mains power),
|
|
- a game is running,
|
|
- pacman's database is locked or another package manager is running.
|
|
|
|
The machine will obviously **never** automatically restart (this is not windows)
|
|
|
|
## Safety measures
|
|
|
|
- A **progress bar** shows which step is running and which package is being updated.
|
|
- **Suspend and shutdown are blocked** via `systemd-inhibit` during updates.
|
|
- A `db.lck` left by a crash is removed on the next run.
|
|
- On Btrfs with `snapper`/`snap-pac` (the CachyOS default), every transaction
|
|
gets a pre/post snapshot.
|
|
|
|
## Package conflicts
|
|
|
|
`AutoResolveConflicts=yes` (default) retries conflicting package replacements
|
|
automatically.
|
|
|
|
File conflicts (`exists in filesystem`) are **not** force-overwritten.
|
|
Signature failures trigger one keyring refresh and one retry.
|
|
|
|
## Logs
|
|
|
|
```bash
|
|
cachy-auto-update log # last run
|
|
cachy-auto-update log -a # rolling log
|
|
journalctl -u cachy-auto-update
|
|
```
|
|
|
|
## Building from source
|
|
|
|
```bash
|
|
make && sudo make install
|
|
sudo systemd-sysusers && sudo systemd-tmpfiles --create
|
|
sudo cachy-auto-update enable
|
|
```
|
|
|
|
`make check` runs shellcheck, syntax checks, and validates the sudoers drop-in.
|
|
|
|
Optional runtime dependencies (degrades gracefully without them):
|
|
`pacman-contrib`, an AUR helper, `flatpak`, Gear Lever, `libnotify`,
|
|
`python-gobject`.
|
|
|
|
## Relationship to cachy-update
|
|
|
|
[cachy-update](https://github.com/CachyOS/cachy-update) is CachyOS's
|
|
interactive updater which checks for updates and notifies, but that needs manual intervention.
|
|
This is the unattended counterpart. The two can coexist; `enable` offers
|
|
to switch off cachy-update's notification since it becomes obsolete.
