also have a look at
/var/log/yum.log
it is in time/data order
newest at the end
you will find on fedora that the GUI's update / "install and remove software"
is basically worthless
the terminal is your FRIEND
and use yum for updates and installing software
see the manual and help pages
Code:
su -
yum --help
====== and the man page =======
man yum
hit the <q> button to exit the manual
BUT BE WARNED !!!
fedora is dropping support for "yum"
they are moving to DNF as the program to use
so in fedora 22 ( currently out) dnf is used
