I don't get why in CI we get

Error: No matching release found for phpunit!

while locally I was able to install PHPUnit

➜  tokenizer git:(uo) tools/phpunit --version
PHPUnit 10.5.60 by Sebastian Bergmann and contributors.

(in CI phive results are different based on php version. in some jobs it works like expected in others it reports "no matching release", in others there are some gpg errors)

I'm not sure why it exits with "code 1"? Having no coverage driver should not be a problem - or should it?
