nette/schema v1.2.3 requires php >=7.1 <8.3 -> your php version (8.3.3) does not satisfy that requirement.

I updated packages on Mint like a good boy, and now I'm getting complaints from composer when building a project, because PHP version is too new.

composer says:

Your lock file does not contain a compatible set of packages. Please run composer update.

And:

Problem 1

• nette/schema is locked to version v1.2.3 and an update of this package was not requested.
• nette/schema v1.2.3 requires php >=7.1 <8.3 -> your php version (8.3.3) does not satisfy that requirement.

Problem 2

• nette/utils is locked to version v3.2.9 and an update of this package was not requested.
• nette/utils v3.2.9 requires php >=7.2 <8.3 -> your php version (8.3.3) does not satisfy that requirement.

Problem 3

• nette/schema v1.2.3 requires php >=7.1 <8.3 -> your php version (8.3.3) does not satisfy that requirement.
• league/config v1.2.0 requires nette/schema ^1.2 -> satisfiable by nette/schema[v1.2.3].
• league/config is locked to version v1.2.0 and an update of this package was not requested.

Running composer update usually causes a world of pain.
