Can't install using composer 2

[garak]

I know that this is probably composer's fault, but I'd like to try anyway here.
In my current situation, I'm using ergebnis/composer-normalize 2.10.0 and ergebnis/json-printer 3.1.1

I would update vendors, but a "composer update" results in:

Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - ergebnis/composer-normalize[2.10.0, ..., 2.11.0] require ergebnis/json-printer ^3.1.1 -> found ergebnis/json-printer[dev-main] but it does not match the constraint.
    - Root composer.json requires ergebnis/composer-normalize ^2.10 -> satisfiable by ergebnis/composer-normalize[2.10.0, 2.11.0].

It's like composer can't find correct versions for this library, looking for "dev-main"

I event did a differen try, creating an empty dir and executing "composer init --no-interaction && composer require ergebnis/json-printer".
This is working with composer 1, not working with composer 2 with following error:

[InvalidArgumentException]                                                                                                                                                         
  Could not find a version of package ergebnis/json-printer matching your minimum-stability (stable). Require it with an explicit version constraint allowing its desired stability

It seems like composer 2 does not find all available versions of this package

$ composer req ergebnis/composer-normalize
Using version ^2.11 for ergebnis/composer-normalize

  Problem 1
    - Root composer.json requires ergebnis/composer-normalize ^2.11 -> satisfiable by ergebnis/composer-normalize[2.11.0].
    - ergebnis/composer-normalize 2.11.0 requires ergebnis/json-printer ^3.1.1 -> found ergebnis/json-printer[dev-dependabot/composer/phpstan/phpstan-0.12.54, dev-main] but it does not match the constraint.

$ composer req --dev ergebnis/json-printer:3.1.1

  Could not find package ergebnis/json-printer in a version matching 3.1.1  

composer v1

$ composer show -a ergebnis/json-printer
...
versions : 3.1.1, 3.1.0, 3.0.2, 3.0.1, 3.0.0, 2.0.1, 2.0.0, 1.1.0, 1.0.0, dev-main, dev-dependabot/composer/phpstan/phpstan-0.12.54

composer v2

$ composer show -a ergebnis/json-printer
...
versions : 9999999-dev, dev-main, dev-dependabot/composer/phpstan/phpstan-0.12.54

and just an instant later:

$ composer show -a ergebnis/json-printer
...
versions : 9999999-dev, * 3.1.1, 3.1.0, 3.0.2, 3.0.1, 3.0.0, 2.0.1, 2.0.0, 1.1.0, 1.0.0, dev-main, dev-dependabot/composer/phpstan/phpstan-0.12.54

I had this changing back and forth today. I did composer clear quite often. I wonder what is going on.

Should we file an issue on composer repo?
