That is ignorable. The functionality previously provided by that package 
is included in php as of 7.2.0. This could be checked in the installer 
script via checking the output of php -i | grep "sodium support => 
enabled". The failing part of the installer script has no further 
consequences.

This happens because the installer runs :

apt -y install php${MAXPHP}-json php-json

but if PHP${MAXPHP}-json does not exist the entire command fails, and no 
php-json package is installed. However, the php website says json 
support is a core extension since 8.0.0 anyway so a better approach 
might be:

1) check php -i | grep "json support => enabled" first
2) if missing, do

for PKG in php${MAXPHP}-json php-json ; do apt -y install $PKG; done

to ensure the entire apt command isn't skipped if one of those packages 
doesn't exist.

I don't think either of these installer script errors were related to 
the problem that Jose reported.
