The installation script fails

[Andrealecce]

OS: Ubuntu 20.04
The installation script returns these two errors
1- "dpkg: error processing archive /tmp/libpng12.deb (--install):
unable to install new version of '/lib/x86_64-linux-gnu/libpng12.so.0': No such file or directory"
2- "/home/mini_cs/php/sbin/php-fpm: error while loading shared libraries: libssl.so.1.0.0: cannot open shared object file: No such file or directory'"

I tried installing any missing libraries in the github readme, but nothing changed. How can I fix this?

Use Ubuntu 18, works like a charm
