well, needed to get deb packages, manually unpack them, fix install script, make manually few symlinks, and use vesta-php binary instead of hestia-php : https://pastebin.com/vTau87RH
this is not an actual install script, it’s side-notes i made while manually typing commands, but u r welcome to finalize it and use it.
also, i very much dislike new ui, so i’ve copied back vesta’s frontend php & css files
so, i have fully functional hestia on centos 8 (php 7.4 & percona), and’d be glad to participate in making official install script for centos. (including to compile binary that isn’t relying on libcurl-gnutls.so…)
