Cannot start parity - "curl" binary not found

Description

Running ethnode parity fails with error.

Version used:

$ ethnode --version
0.0.17

Parity already is available in my path, meaning I can run parity to connect to the main Ethereum network. I also have geth in my path.

My operating system is Arch Linux:

$ uname -a                    
Linux cola 5.0.9-arch1-1-ARCH #1 SMP PREEMPT Sat Apr 20 15:00:46 UTC 2019 x86_64 GNU/Linux

Current shell zsh:

$ echo $SHELL              
/usr/bin/zsh
$ zsh --version      
zsh 5.7.1 (x86_64-pc-linux-gnu)

Hi @cleanunicorn, thanks for reporting your issue. When ethnode starts for the first time, it downloads a new binary (geth or parity) and place it in a cache directory. The script to download parity is a ripoff of this one https://get.parity.io/, so if the original one works, mine should work as well 🤞, but I see this is not what's happening here.

Can I ask you to run the install script manually? Here you are basically triggering the download of parity by hand:

git clone https://github.com/vrde/ethnode.git
cd ethnode
HOMEDIR=/tmp ./get_parity.sh

If it still fails, try removing from line 92 to line 98 in get_parity.sh with your editor or with:

sed -i -e '92,98d' get_parity.sh

and then run again:

HOMEDIR=/tmp ./get_parity.sh

You can also force the download with ethnode -d parity

Hello @vrde!

The parity download scrips works well and as I said, I already have parity available in the path.

The problem should be in: "curl" binary not found, please install and retry. Don't know the reason why it is not available when running ethnode parity, while curl is available if you run get_parity.sh manually 🤔

I've just released version 0.0.18 but it shouldn't make any difference for this issue.

I've intsalled ethnode successfully on other GNU/Linux machines, and also on Mac. I'd like to help you more, but I don't have ideas for now.
