So I did yum update last night because I decided that I should update whatever packages I could. Big mistake.Now I can't undo the changes, and it's not telling me why. I am trying to undo 65 (as shown via yum history):   ID | Login user          | Date and time    | Action(s)      | Altered   65 | My User <guy>       | 2016-12-08 18:07 | I, O, U        |  800 EE   64 | My User <guy>       | 2016-12-08 17:44 | Erase          |    1      63 | My User <guy>       | 2016-12-08 17:29 | Update         |    1 So I do yum history undo 65. And at first it looks okay, giving me stuff that looks like:Updated     ConsoleKit-0.4.1-3.el6.x86_64                                  @anaconda-CentOS-201311272149.x86_64/6.5Update                 0.4.1-6.el6.x86_64                                  @baseUpdated     ConsoleKit-libs-0.4.1-3.el6.x86_64                             @anaconda-CentOS-201311272149.x86_64/6.5Update                      0.4.1-6.el6.x86_64                             @baseUpdated     ConsoleKit-x11-0.4.1-3.el6.x86_64                              @anaconda-CentOS-201311272149.x86_64/6.5Update                     0.4.1-6.el6.x86_64                              @baseUpdated     NetworkManager-1:0.8.1-66.el6.x86_64                           @anaconda-CentOS-201311272149.x86_64/6.5Update                     1:0.8.1-107.el6.x86_64                          @baseUpdated     NetworkManager-glib-1:0.8.1-66.el6.x86_64                      @anaconda-CentOS-201311272149.x86_64/6.5Update                          1:0.8.1-107.el6.x86_64                     @baseUpdated     NetworkManager-gnome-1:0.8.1-66.el6.x86_64                     @anaconda-CentOS-201311272149.x86_64/6.5Update                           1:0.8.1-107.el6.x86_64                    @baseBut after all of that it's nothing but:Failed to downgrade: ConsoleKit-0.4.1-3.el6.x86_64Failed to downgrade: ConsoleKit-libs-0.4.1-3.el6.x86_64Failed to downgrade: ConsoleKit-x11-0.4.1-3.el6.x86_64Failed to downgrade: 1:NetworkManager-0.8.1-66.el6.x86_64Failed to downgrade: 1:NetworkManager-glib-0.8.1-66.el6.x86_64Failed to downgrade: 1:NetworkManager-gnome-0.8.1-66.el6.x86_64...Error: No package(s) available to installAnd it doesn't tell me why or what to try so I am lost. When I try yum downgrade x-package it tells me Only Upgrade available on package: x-package.Edit 2: If it had worked, I should have seen yum action 66 shouldn't I?
