FireAlpaca has an AppImage, but it's only compatible with Glibc-based distros and it can be jank to manage it. If you want a more portable format or can't use the AppImage due to being on Alpine, Chimera, or another Musl distro, this script will extract the appimage and install it portably as a Flatpak for you.

Requirements

flatpak & flatpak-builder
wget
fuse and its libraries

How to use

Sudo/doas perms are not required to run this script. It will build the Flatpak rootless.

git clone codeberg.org/gigirassy/firealpaca-flatpak --depth 1
chmod +x install.sh
./install.sh

After, make a desktop entry with these contents if you'd like:

[Desktop Entry]
Type=Application
Name=FireAlpaca
Comment=FireAlpaca
Exec=/usr/bin/flatpak run com.firealpaca.FireAlpaca
Icon=/home/nune/.local/apps/firealpaca/icons/firealpaca
Terminal=false
Categories=Graphics;
X-AppImage-Version=2.14.0

Then update your database: sudo update-desktop-database # or doas
