Hi, I'm currently working on my next Linux book, which will be an elementary course about CentOS administration. I'm using VirtualBox for all the installer screenshots. Since CentOS has recently been upgraded to version 7.6, I thought I might as well base all book references on this version. So I downloaded the 7.6 1810 minimal ISO and started a fresh installation in VirtualBox. I'm using a Swiss French keyboard layout (ch-fr or fr_CH-latin1), so one of the first things I do in the installer is replace the default French AZERTY keyboard (since I use the french language) by a swiss french QWERTZ layout. Now when I reach this dialog in the installer and try do define my new layout, the slider in the selection window doesn't appear, and clicking on any of the first layouts doesn't do anything, so I'm basically stuck there. I'm running OpenSUSE Leap 15.0 KDE on my workstation, so I tried the same thing with the previous CentOS 7.5 1804 minimal ISO, and the keyboard selection dialog works perfectly. So my intuition would tell me that there's a nasty bug in the CentOS 7.6 installer. Maybe it went unnoticed, since most folks stick to the default keyboard layout selected in their language. Any suggestions ?
