Please help me
I never get this actually after many many times installing hestia
after recheck your screenshot, try to set the FQDN rite, such as your domain and A record
maybe can help you out
sudo apt-get update --fix-missing
sudo apt-get install -f
sudo apt-get update
sudo apt-get autoremove
sudo apt-get clean
then tray install hestia again.
Hestia only supports amd64/x64 systems, do you try to install it on x86 or arm?
I had that issue some days ago and this fixed it
For others to spare many hairpulling searches for solving a failing installation script, this may help.
Maybe a little late, but I found that after enabling all the available repositories ( i.e. main, restricted, universe, and multi-verse ) the installer script was successful.
