Bug 1979048 https://bugzilla.redhat.com/show_bug.cgi?id=1979048

TLDNR:

Fedora 34, updated from Fedora 33 and using zsh.   System has been updated
using dnf.

zsh uses:

PackageKit-command-not-found.x86_64 : Ask the user to install command line
programs automatically

% xindy
zsh: xindy: command not found...
Failed to search for file: repo_add_solv() has failed.

This should offer to install the texlive-xindy package.
