council to modify the installation script given the problems encountered with the MAIN installation, starting from an ubuntu 18 machine which by default has a mysql bug where the pwd remains empty, you could add the mariadb 10.2 or 10.3 repos of your choice, install mariadb-server and not mysql since almost all v2 run on mariadb engine and then rectify my.cnf where the default values are too high for 20000 connections if the uses innodb_buffer_pool_size = 10G would mean having a machine with at least 256gb of ram then absolutely wrong as a defaults file (my.cnf), then we can add the libcurl34 repo so that we can use both libcurl libraries 3 and 4 and then also phpmyadmin where with 2 fixes in the conf php of the database works perfectly. Obviously before inviting us to consider these changes, I managed them on my server and it worked perfectly!
