I’ve tried pacman -S gscan2pdf, but get error: target not found. Can anyone help?
Can I get gscan2pdf?
Wow, had a hell of a lot of lines, some asking if I wanted to edit something, hit NO for all of them, yes for all other install prompts. Are AUR installs always so ‘long’?
AUR are used contributed packages, so no guarantee is provided. That long text is the PKGBUILD, that instructs how the package must be installed.
Is your responsability to check what the package will install into your system (and what will modify).
Don’t worry, though. Most of the time is fairly safe.
