kikadf commented on 2016-08-20 12:50 (0) wrote Don't undesrtand your problem. Why do you want to install notifier-frameworks and notifier-qt*?

First remove old notifier-0.8.1. (conflict with new notifiers)
If you use kde5, install only notifier-frameworks.
If you use other, but you have qt5, install only notifier-qt5.
If you use other, but you have qt4, install only notifier-qt4.
Other then irrelevant dbus compile errors on my end, I can not reproduce your problem

Try this:
cd ~
mkdir -p build-tmp; cd build-tmp
yaourt -G octopi; makepkg -sirc
sudo pacman -U octopi-0.8.3-1-x86_64.pkg.tar.xz
cd -; rm -rfv build-tmp

The post was deplaced from bug report forum, why? :

First, please make a new post when you have a particular problem instead of posting on existing one which do not concern the same problem.
Second, this is not a bug here but a misunderstanding from your part. So posting on bug report is not a good idea. A problem can be considered as bug when the trouble can be reproducible on the same way on every machine, not the case here.
Third, as it said on the obarun home page site, Obarun is not designed with beginners to Linux in mind, that's mean : if a beginners in linux want use it , he must learn the base of linux command, he must learn how to use console, he must learn how to work pacman, he must learn how to maintain its own system, he must make its own research and understand a command before using it and so one...

So, you can find help here but applying a command without searching what the command mean and how it works is a very bad idea and that is right for every system you use, not in particular on obarun.

Well, try the given command by bit one by one:
mkdir -p tmp/build-octopi
then
cd  tmp/build-octopi 
yaourt -G octopi
and now, what happen on the directory tmp/build-octopi?
ls
obarun@ obarunS6 build-octopi % ls
octopi/
so as you can see yaourt maded a new folder containing all the necessary to build octopi, you need to place you on the new folder.
cd octopi
now (a very good idea here is to read the man page of makepkg, to know exactly what you made with the bit command, or mine)
makepkg -src

now you can install the desired package with pacman -U command (same thing here, man pacman) :
sudo pacman -U name_of_the_package
So as you can see your trouble is very easy to solve and do not need to ask some help if you think a minimum

no that easy !
 # pacman -U octopi

error: 'octopi': could not find or read package

:rolleyes :
# pacman -U /xxx/tmp/build-octopi/octopi/octopi-0.8.3-1-x86_64.pkg.tar.xz
