How long has this problem existed?

Since upgrading to php7.4, they will fix it in while, you should install Joomla manually through Ftp instead


I uploaded the latest version of Joomla from ftp but it does not allow installation

What’s the error log when trying to upload and installing it using FTP?

As what Joomla checked there is currently no Zlib compression support since read the announcement @anon19508339 provided above that there is an issue with Zlib meaning you can’t currently install Joomla if it doesn’t let you install it without the Zlib compression module or something.
