Your requirements could not be resolved to an installable set of packages.
Problem 1
- Root composer.json requires PHP extension ext-krb5 * but it is missing from your system. Install or enable PHP's krb5 extension.
Problem 2
- Root composer.json requires simplesamlphp/simplesamlphp-module-negotiate ^2.1.0 -> satisfiable by simplesamlphp/simplesamlphp-module-negotiate[v2.1.0].
- simplesamlphp/simplesamlphp-module-negotiate v2.1.0 requires ext-krb5 >=1.1.4 -> it is missing from your system. Install or enable PHP's krb5 extension.
To enable extensions, verify that they are enabled in your .ini files:

You can also run `php --ini` in a terminal to see which files are used by PHP in CLI mode.
Alternatively, you can run Composer with `--ignore-platform-req=ext-krb5` to temporarily ignore these required extensions.
