no, I tried again minutes ago and now the installation is OK; I'm on x86_64

AFAIU this time the package ghc-8.10.7 was installed as a substitute and
not locally compiled.

Anyway, I also tried to build ghc-8.8.4:

I really don't understand why on Friday the very same build failed.

Anyway I'm going to close this bug report: thanks!

Happy hacking! Gio'
