# Pacroller
|
|
The "Unattended Upgrades" for Arch Linux.
|
|
|
|
## Concept
|
|
Parsing the output of pacman and pacman.log, searching for known patterns and notifying the user whether there is a potential error.
|
|
Currently the design is regex-based, any output that is unable to match a set of regex is reported back to the user.
|
|
|
|
## Installation
|
|
`yay -S pacroller`
|
|
|
|
## Usage
|
|
pacroller has the following subcommands
|
|
```
|
|
run [-d --debug]
|
|
start an upgrade
|
|
if the upgrade fails or pacroller determines that human action is required,
|
|
pacroller writes an exception to the status database, and refuses to run again
|
|
without resetting its failure status.
|
|
status [-v --verbose] [-m --max <number>]
|
|
print details of a previously successful upgrade
|
|
reset
|
|
reset the current failure status
|
|
test-smtp
|
|
send an test email to the configured address
|
|
```
|
|
There is also a systemd timer for scheduled automatic upgrades.
|
|
|
|
## Configuration
|
|
Pacroller reads `/etc/pacroller/config.json` on startup.
|
|
### custom sync commands
|
|
Pacroller can be configured to use custom sync commands, which allows the usage of a different set of mirrors when syncing the database. Enable the "custom_sync" option and write your custom `/etc/pacroller/sync.sh`.
|
|
### needrestart
|
|
If the "needrestart" option is enabled, needrestart should be called after a successful upgrade.
|
|
### hold packages
|
|
Put your hold packages in a json keyval {package name: regex}, where the regex should have at least one matching group.
|
|
If pacroller observes any changes of the matching group or the hold package is to be removed, it refuses to upgrade further.
|
|
### ignored pacnew
|
|
A list of pacnew files that are silently ignored during parsing, any other pacnews will trigger a warning and prevent further upgrades.
|
|
### custom pacman hooks and packages
|
|
Custom pacman hooks and packages output matching is configurable via `/etc/pacroller/known_output_override.py`.
|
|
### check systemd status
|
|
The "systemd-check" option allows pacroller to check fo degraded systemd services before an upgrade.
|
|
### clear package cache
|
|
Pacroller wipes /var/cache/pacman/pkg after a successful upgrade if the option "clear_pkg_cache" is set.
|
|
### save pacman output
|
|
Every time an upgrade is performed, the pacman output is stored into /var/log/pacroller. This can be configured via the "save_stdout" keyword.
|
|
|
|
## Smtp
|
|
Configure `/etc/pacroller/smtp.json` to receive an email notification when an upgrade fails. Note that pacroller will not send any email if stdin is a tty (can be overridden by the `--interactive` switch).
|
|
|
|
## Limitations
|
|
- Your favourite package may not be supported, however it's easy to add another set of rules.
|
|
- Restarting the whole system after a kernel upgrade is not implemented.
|
|
- Human interaction is required occasionally.
|
|
- Does not check news from archlinux.org
