Comment 2 for bug 1595008

This is my procedure for mint 18:

We need the gambas3 PPA for Mint 17. The copy of gambas3 from the Mint 18 repos will not work with i-nex.
Open a terminal and copy and paste each line:
>sudo add-apt-repository ppa:gambas-team/gambas3
>sudo apt update

We will need to download an ubuntu 14.10 deb file to install i-nex. The official i-nex PPA does not support Mint 18, yet.
Download one of these installers:
64bit installer: https://launchpad.net/i-nex/trunk/7.4.0/+download/i-nex_7.4.0-0%7Ebzr855%7E20140813%7Eubuntu14.10.1_amd64.deb
32bit installer: https://launchpad.net/i-nex/trunk/7.4.0/+download/i-nex_7.4.0-0%7Ebzr855%7E20140813%7Eubuntu14.10.1_i386.deb

I-nex fix:

The post install script for i-nex may fail with an error. I would not normally provide a fix for a such a problem, but this error is coming from a post install script and causes the entire OS to give off errors everytime a new piece of software is installed which is totally unacceptable. The script doesn't do anything but tell their website one more copy has been installed. This fix does not prevent the script from running or modify what it does. It simply returns an exit status of ZERO which means everything went well so that Linux will stop complaining.

Open the post install script with a text editor and add the "exit 0" line to the end of the script.
Open a terminal and copy and paste:
>sudo nano /var/lib/dpkg/info/i-nex.postinst

#!/bin/bash if which curl >/dev/null; then
                                                                    curl --silent https://i-nex.linux.pl/?downloadcount=1 > /dev/null 1>&1
fi
exit 0

CTRL-o and then ENTER to save. CTRL-x to exit NANO.

And then the following to make the error go away:
>sudo apt-get install -f
