The module is not correctly imported due to ... case sensitivity nature of Linux.

The names of modules in the module manifest need to be case sensitive.
RequiredModules = @('pester','pscribo').

[alagoutte]

It is fixed with commit dad932f ?

[it-praktyk]

Unfortunately, PScribo (which is heavily used by Format-Pester) is not PowerShell Core compatible. So I can't state that Format-Pester works on PSCore as well.

Ok but it is PScribo issue... (and look only about return line), there is a no issue or PR for fix PScribo ?

[alagoutte]

Pscribo can be run now with PowerShell Core :)

[it-praktyk]

Yes, it's true. I've checked that yesterday. When the version > 0.7.26 of PScribo will be released I'll update Format-Pester.
