That's strange. Unfortunately I don't know enough about Fedora to give any concrete advice here; it does look like that's the correct package. Have you tried uninstalling the package first, and/or forcing its installation?

You can get the Perl source at https://www.perl.org/get.html#unix_like, as well as precompiled binaries, although in my experience those are rarely needed on *NIX. You can theoretically build a system Perl from scratch, but I'm pretty sure using Fedora's packages will be better in the long run.

Tried that. Installed ActivePerl-5.28.1.0000-x86_64-linux-glibc-2.12-f7fd6fde in default directory /opt/ActivePerl-5.28 but no command perl unless its the link perl -> perl-static or perl5.28.1 -> perl-static. There is nothing in my path linked to them. Typically, in past installations, the perl command is in /usr/bin/. My perl programs all point to that location (#!/usr/bin/perl -w) .

Tried that.

Perhaps you could post the output of dnf --verbose reinstall perl-interpreter, maybe even as a new question for better visibility.
