It looks like zPanel’s installer checks if you’re running Ubuntu 12.04, but does not care if you’re running e.g. 12.04.5. zPanel itself should work on Ubuntu 12.04.5 so I would suggest removing the “12.04” check in the installer.

Download the installer:

wget -O install_zpanel.sh https://raw.githubusercontent.com/zpanel/installers/master/install/Ubuntu-12_04/10_1_1.sh
chmod +x install_zpanel.sh

Then, open it in an editor and delete lines 61-66:

if [ "$OS" = "Ubuntu" ] && [ "$VER" = "12.04" ]; then
  echo "Ok."
else
  echo "Sorry, this installer only supports the installation of ZPanel on Ubuntu 12.04."
  exit 1;
fi

Or, run the following command to do that:

sed -ie '61,66d' install_zpanel.sh

You should now be able to install zPanel:

sudo ./install_zpanel.sh

Hello, all

I have not personally used zPanel, but to me, this project looks completely abandoned. There have been no updates to that repository for the past 7 years:

https://github.com/zpanel/installers

The last installer script which was supported was for Ubuntu 12, which has been EOF for a very long time:

https://github.com/zpanel/installers/tree/master/install

I would recommend choosing a different control panel. You could start by having a look at this page here for some useful Control panel tutorials:

https://www.digitalocean.com/community/tags/control-panels

There are a lot of web panels available (most of them are free to use) that you can choose in order to manage your server. What I can recommend is to try them as in this way you can see if it really suits your needs.

I will list the top control panels that I recommend:

CentOS Web Panel
Vesta CP
Webmin
Ajenti
ISPConfig

and of course I need to mention Plesk although it’s not free it’s been available for a while and it’s always been the main cPanel competitor. It has a lot of build-in features and a lot of plugins that you can install and you can always reach to their support team if needed which is something that might come in handy in time.

You’ve now got some great options if you want to use a control panel with your server but you don’t want to pay for a license. I’ve tried to layout most of the available options, but which one is best will ultimately depend on your individual needs.

Regards,
Alex
