Error: Package: systemd-219-78.el7_9.3.x86_64 (updates)
Requires: systemd-libs = 219-78.el7_9.3
Installed: systemd-libs-219-73.el7_8.5.x86_64 (@koji-override-1)
systemd-libs = 219-73.el7_8.5
You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
There are other useful transaction flags, but the transaction test is the most useful one, at least for me.
