nss conflicts with nspr in rawhide. Manually uninstalling nspr-devel first makes it work. The dnf claim: Error: Transaction test error: file /usr/share/man/man1/setup-nsssysinit.1.gz from install of nss-sysinit-3.79.0-2.fc37.x86_64 conflicts with file from package nspr-devel-4.34.0-1.fc37.x86_64 file /usr/share/man/man5/cert9.db.5.gz from install of nss-3.79.0-2.fc37.x86_64 conflicts with file from package nspr-devel-4.34.0-1.fc37.x86_64 file /usr/share/man/man5/key4.db.5.gz from install of nss-3.79.0-2.fc37.x86_64 conflicts with file from package nspr-devel-4.34.0-1.fc37.x86_64 file /usr/share/man/man5/pkcs11.txt.5.gz from install of nss-3.79.0-2.fc37.x86_64 conflicts with file from package nspr-devel-4.34.0-1.fc37.x86_64 file /usr/share/man/man1/certutil.1.gz from install of nss-tools-3.79.0-2.fc37.x86_64 conflicts with file from package nspr-devel-4.34.0-1.fc37.x86_64 file /usr/share/man/man1/modutil.1.gz from install of nss-tools-3.79.0-2.fc37.x86_64 conflicts with file from package nspr-devel-4.34.0-1.fc37.x86_64 file /usr/share/man/man1/pk12util.1.gz from install of nss-tools-3.79.0-2.fc37.x86_64 conflicts with file from package nspr-devel-4.34.0-1.fc37.x86_64 file /usr/share/man/man1/signver.1.gz from install of nss-tools-3.79.0-2.fc37.x86_64 conflicts with file from package nspr-devel-4.34.0-1.fc37.x86_64 file /usr/share/man/man1/nss-config.1.gz from install of nss-devel-3.79.0-2.fc37.x86_64 conflicts with file from package nspr-devel-4.34.0-1.fc37.x86_64
This bug appears to have been reported against 'rawhide' during the Fedora Linux 37 development cycle. Changing version to 37.
I'm not sure why nspr-devel wasn't picked up it's part of the NSS package. it's possible you don't have the -devel libraries in RPM?
I had installed nss-devel and nspr-devel. Nonetheless, I cannot reproduce it right now, thus I'm closing this. I'll reopen and will provide more detailed info if it'll strike again.
