Is this ok [y/N]:
@unman: from above test and report, we can see that cacher is actually getting in the way of getting actual updates without manual action.
Having Fedora-36 manually call sudo dnf update without cleaning local Template’s cache and then cacher’s cache reported no updates available, which was a false negative.
Cleaning Fedora-36 cache caused zck mismatch error, which required to clean cacher’s cache.
What can be done to have Fedora templates correctly getting available updates under cacher’s apt-cacher-ng configuration non-applied tweaks?
