Installed 1.8.5 from source on Fedora 37. Make testall shows an error observing that DNS setup seem to be working and suggests installation of libnss-resolve. Libnss-resolve unavailable via dnf search.

Details:  
From worker 11: ┌ Error: `getnameinfo` failed on an unroutable IP address. If your DNS setup seems to be working, try installing libnss-resolve
