The PKGBUILD links 404.

Thx. These were the old AUR3 links; fixed.

I get key errors :
Verifying source file signatures with gpg... cower-16.tar.gz ... FAILED (unknown public key 1EB2638FF56C0C53) ==> ERROR: One or more PGP signatures could not be verified! ==> Making package: pacaur 4.6.3-1 (Thu 21 Apr 16:05:23 BST 2016) ==> Checking runtime dependencies... ==> Installing missing dependencies... error: target not found: cower ==> ERROR: 'pacman' failed to install missing dependencies.
any feedback?

In my experience the keyservers pool is a bit flakey .. it seems you did not successfully receive the gpg key.
Because of that, cower did not install and pacaur had missing dependencies.
@conorbone, try running gpg --recv-keys 1EB2638FF56C0C53 manually beforehand ..

@rumpelsepp, personally I'd just use the default keyserver (currently hkp://keys.gnupg.net) or hkp://pgp.mit.edu
Also, I went back to using curl in my fork. Any reason against it, besides the long links?

I somehow missed the notifications on the Gist. :/
Yeah, we could of course tweak the script a bit. I like your implementation using the loop and I would happily steal that. For git vs curl, it is just my personal taste... But yeah, git is required by pacaur anyway, so I think it does not make any difference.

@rumpelsepp What about --depth=1! 😄

git clone "https://aur.archlinux.org/cower.git" --depth=1
git clone "https://aur.archlinux.org/pacaur.git" --depth=1

That's a suggestion which is definitely worth it. :D

I can't run this script, I get the makepkg as root error:

==> ERROR: Running makepkg as root is not allowed as it can cause permanent, catastrophic damage to your system

You can't build packages as root!! The errormessage describes the problem quite well:

For some reason pacaur is not getting cloned i had to manually clone it on tmp folder and run the script

Can't found pacaur directory in /tmp/

same as above

pacaur is getting cloned inside cower folder adding cd .. before git clone "https://aur.archlinux.org/pacaur.git" should solve the problem

Should be cd "$buildroot" || exit 1 just after the cower makepkg, still inside the if statement (could be after as well I guess). cd .. just before git clone will take you to /tmp on arm builds.

Any ideas how I can get notifications in gist.github.com? I always miss you guys...

The issue should be fixed.

I had the error /bin/sh: pod2man: command not found. Executing the script with $ bash -l then worked.
It seems that the path variable is reset at some point. See here for a similar fix.

Strange. I fixed it accordingly; since I use debian now I cannot test it. So, I hope nothing else breaks. :D

@rumpelsepp Gave this a go today and it's working just fine 👍

I think sudo pacman -S cower also should have the flags --needed --noconfirm
