gentoo-update 0.2.2

Gentoo Linux updater

Gentoo Updater

:warning: Important Update: Version 0.2.2 introduces breaking changes. The CLI has been completely rewritten and now features a subcommands structure. Please review the updated README below to understand the changes and ensure a smooth transition.

gentoo-update is a tool that automates updates on Gentoo Linux. By default it only installs security updates from GLSA, but it can also be used to update all packages on the system, i.e. @world.

This project originates from 2023 Google Summer of Code, more about it can be found in the blog post and Gentoo Forums.

gentoo_update has 3 main modules - updater, parser and notifier. Updater runs the update script and creates a log file. Parser reads the log file and composes a post-upgrade report which notifier then sends via email, IRC bot or mobile app.

Features

updater

• update security patches from GLSA by default, and optionally update @world
• insert additional flags to @world update
• do not start the update if available disk space is lower than a certain threshold
• estimate update time and show package list before the update

parser

• show update status (success/failure) in the report
• show package info after successful update: ebuilds, blocks, uninstalls etc.
• detect different errors during an update
  • blocked Packages
  • USE flag conflicts
  • issues with Licenses
  • network issues during an update
  • OOM during an update
• show disk usage before/after an update

notifier

• send update report via IRC bot
• send update report via email using SendGrid
• send update report via email using local relay
• send update report via mobile app
• send a short report with only the update status instead of a full report

general

• CLI: add option to choose from which log file to generate a report
• CI/CD pipeline that will run gentoo_update on newly published stage3 Docker containers
• comprehensive set of unit tests

Installation

gentoo-update is in GURU overlay, and can be installed using emerge. First, enable the overlay:

emerge --ask app-eselect/eselect-repository
eselect repository enable guru
emerge --sync

All packages in GURU overlay need an ~arch keyword. For example, on amd64 architecture add it using:

echo 'app-admin/gentoo_update ~amd64' > /etc/portage/package.accept_keywords/gentoo_update

and then install it:

emerge --ask app-admin/gentoo_update

Alternatively, it can be installed with pip in a virtual environment:

python -m venv gentoo_update
source gentoo_update/bin/activate
python -m pip install gentoo_update

Usage

The updater creates a subdirectory in Portage's default PORTAGE_LOGDIR located at /var/log/portage/gentoo-update. However, if this variable is set to a different value in make.conf, it will use the new location instead of the default.

Here are some usage examples:

• Basic security update

gentoo-update update

• Full system update with extra update parameters

gentoo-update update -m full -a "--color=y --keep-going --exclude=glibc"

• Full system update, show elogs and news

gentoo-update update -m full -l -n

• Read last update report:

gentoo-update report

• Show the last 3 logs filenames, and generate a report for one of it:

# gentoo-update report -o 3
The last 3 log file filenames
log_2023-09-23-09-19
log_2023-10-02-20-19
log_2023-10-07-13-14
# gentoo-update report -r log_2023-10-02-20-19
==========> Gentoo Update Report <==========
update status: SUCCESS
......

• Send the last update report to an IRC channel:

export IRC_CHANNEL="#<irc_channel_name>"
export IRC_BOT_NICKNAME="<bot_name>"
export IRC_BOT_PASSWORD="<bot_password>"
gentoo-update report -s irc
