An hour?! Most of my offline updates take a few tens of seconds with
F21. Is this on fairly up-to-date SSD hardware? Are any specific
packages taking longer than the others?
an hour was surely exaggerated
but there was not so long ago a bug in some package updateing caches
which took on a hyperfast RAID10 machine with enabled barriers up to 10
minutes for a ordinary KDE update
before it got fixid without barriers (which are are default) a few
seconds - you don't know if and how often such things may get triggered
inside a update transaction (like the useless ldconfig and systemd
reloads after every single related package)
