/var/lib/flatpak/repo/objects using up /var partition

[Michael Hennebry]

After my most recent sudo dnf upgrade ,
/var/lib/flatpak/repo/objects is using up most of my /var partition.
sudo dnf clean all did not help.
Previously when my /var ran low,
the problem was a directory named cache that I could just remove.
Not this time.

What can I do to reclaim somme room for my /var partition?
I've never used flatpak intentionally or directly.
