Thank you. Your suggestion worked!
Here were the final two commands:
chmod +x hst-install-debian.sh
then
./hst-install-debian.sh --with-debs /root/
For others wanting to install Hestia 1.4 beta on a Debian 10 server, these are the commands for the two dependencies you may need to install before installing Hestia:
sudo apt-get install zstd
Then
sudo apt install sysstat
sudo nano /etc/default/sysstat
Change the variable “ENABLED” from “false” to “true”
exit the nano editor after saving the file.
sudo systemctl enable sysstat
sudo systemctl start sysstat
sudo systemctl status sysstat
Then type q to close the screen.
I am now exploring Hestia 1.4 beta. So far, it looks pretty good. Thanks again for your help.
