F41 -> F42 mysticism

[Frank Elsner]

Hallo,
      the following problem applies to both of my F41 systems:

After "dnf system-upgrade download --refresh --releasever=42"
directory /usr/lib/sysimage/libdnf5/offline/packages contains
all downloaded packesges.

Idid it yesterday afternoon, and this morning the directory is empty.
AWhat happend? to the packages how to do analysis of the remove.
