> 2020-03-14 13:10:05,654 DEBUG running apport_pkgfailure() libc6: 0.1332:il sottoprocesso installato pacchetto libc6:amd64 script post-installation ha restituito lo stato di errore 127

Can you please show the apt term log from this upgrade?

It is concerning that the log you posted so far does not show libcrypt1 being installed, despite this being a dependency of libc6. Did you already have libcrypt1 installed, and at what version?
