update-fastfetch

Keep fastfetch up to date on Debian. Fetches the latest release from GitHub and installs it, skips the download when you are already current. Works for manual runs as well as provisioning and cron.

Features

• Installs or upgrades fastfetch to the latest GitHub release
• Skips the download entirely when the installed version is up to date
• Detects the architecture (amd64, armv6l, armv7l, arm64), including Pi Zero/1 that report armhf but only run armv6
• Runs as a normal user (sudo only when installing) or as root
• Only needs curl, apt-get and mktemp

Debian, Ubuntu, DietPi and Raspberry Pi OS are the tested targets. Other distributions may work if they take .deb packages.

Usage

git clone https://github.com/mews-se/update-fastfetch.git
cd update-fastfetch
chmod +x updatefastfetch.sh
./updatefastfetch.sh

No sudo needed on the command line, the script elevates by itself when it is time to install. Packages are downloaded to /tmp and cleaned up afterwards.
