Issue installing cyberpanel (pure ftpd issue)

I am trying to install latest cyberpanel on fresh centos 7 minimal
openvz vps with command:
sh <(curl https://cyberpanel.net/install.sh || wget -O -
https://cyberpanel.net/install.sh)

The installation is failing at the point of starting pure-ftpd.

How can I fix this?

After a lot of digging it looks like the issue is actually related to the kernel of openvz being old 2.6 which creates an issue with centos 7.7
