#!/bin/bash

#Make sure the system is up to date.
sudo pacman -Syu --noconfirm


#Install dependency packages we'll need to build Pacaur on Arch.
sudo pacman -S binutils make gcc fakeroot expac yajl git --noconfirm


#Create a temporary working directory for installing Pacaur.
mkdir -p ~/tmp/pacaur_install
cd ~/tmp/pacaur_install


#Install pacaur from AUR: Download the files from git and build a .tar.xz file then install it.
curl -o PKGBUILD https://aur.archlinux.org/cgit/aur.git/plain/PKGBUILD?h=pacaur
makepkg -i PKGBUILD --noconfirm

#Now clean up system: deleting temporary directory.
rm -r ~/tmp/pacaur_install

Troubleshooting 1

If you run into trouble with specific dependencies, install them first using pacman:

sudo pacman -S your_dependency

Troubleshooting 2

I also bumped into another dependency issue related to auracle-git

• https://aur.archlinux.org/packages/auracle-git/

You will have to build it from source and here are the steps:

1. Use wget to get the auracle-git.

wget https://aur.archlinux.org/cgit/aur.git/snapshot/auracle-git.tar.gz

2. Uncompress auracle-git:

tar -xzf auracle-git.tar.gz

2. Build the package:

cd auracle-git
makepkg PKGBUILD --skippgpcheck --noconfirm

3. Use pacman to build the already generated package:

pacman -U auracle-git-*

4. Re run install_pacaur.sh to install pacaur:

./install_pacaur.sh

Troubleshooting 3

$VISUAL and $EDITOR environment variables not set or defined editor not found

1. Add to ~/.bashrc file the EDITOR variable :

export EDITOR="/usr/bin/vim" 

2. And then:

source ~/.bashrc

I am trying install the pacaur using your script and the following error is showed to me:

hi !

Cower is no longer available. u need tu use another way =)

btw trizen > pacaur =)

@StarleyRibeiro check the Threshold section right below the script. As @psykoterro pointed out cower is no longer available but in its replacemente you use Auracle.

Related to trizen I have not tried it yet but I'm happy with pacaur, especially because of the CLI commands are a replica from the built-in pacman.

Everything should work if you follow up the steps below. Let me know. @psykoterro thanks for the comment :).

@android10

Hi again,

I have installed cower package from following link: http://archlinuxgr.tiven.org/archlinux/x86_64/cower-18-2-x86_64.pkg.tar.xz.
I could notice the following library is missing in system: "libffi"
I have installed using pacman and just now, everything I try executing, the following error is displayed:

[starley@HP-EliteBook8460p ~]$ mousepad
mousepad: error while loading shared libraries: libffi.so.6: cannot open shared object file: No such file or directory

after doing a graceful reboot, I could notice the system is breaked (kernel panic).

Someone could help me out with this!?

@StarleyRibero I have the Troubleshooting 2 that explains step by step how to install auracle. Cower is not necessary anymore. That might have caused your issue.

I would remove what you installed with:

pacman -Rns "your_package"

Then do a fresh install as detailed here but without installing cower, you do not need it anymore.

@android10

Hi again,

Tks a lot for your feedback. I followed the suggestion of psykoterro and installed the trizen. I had no troubles during instalation and apparently, everything is fine so far.

I just have one point of consideration of related to trizen, it's written in pear, and I preffer (that's my oppinion) package managers which are writter in bash, because that's the native language of shell, but I can survive with this.

I another situation will try again to install pacaur.

brgds,
Starley

I'm following your steps. I'm at makepkg PKGBUILD --skippgpcheck --noconfirm I got this error

I installed all the dependencies as you said that were missing.

hey @aiky967 I would suggest to use yay or paru, pacaur has not been maintained for a while so I would suggest to the other alternatives.
