Install a ppc64 (Big Endian) machine with anaconda using vnc and click on help windows displays a blank window without any text. iso image used: https://dl.fedoraproject.org/pub/fedora-secondary/releases/test/24_Beta/Server/ppc64/iso/Fedora-Server-dvd-ppc64-24_Beta-1.6.iso I was not able to get any debug traces except following line in syslog: 16:08:05,630 INFO kernel:[ 110.026779] WebKitWebProces[3398]: unhandled signal 11 at 0000000000000000 nip 00003fffa61bf774 lr 00003fffa61c4398 code 30001 I tried to recreate using command: anaconda -G --dirinstall /var/tmp but I was not able to connect to vnc server (error: Unknown VeNCrypt authentication scheme from VNC server: 1)
Anaconda uses Yelp to display the help, which IIRC uses Webkit, which is what apparently crashes. Could you maybe check if you can launch Yelp on the installed system ? Also adding the Yelp maintainer to CC.
I found yelp trace in program.log: INFO program: Running... yelp /usr/share/anaconda/help/en-US/WelcomeSpoke.xml I exported the display to my remote pc and run the following yelp command in the anaconda console: yelp /usr/share/anaconda/help/en-US/WelcomeSpoke.xml I got the help window on my remote xterm pc but it is still blank and still got WebKitWebProces crash.
This issue exist in F24, ppc64, RC 1.1 iso installation as well. ISO used is http://ppc.koji.fedoraproject.org/compose/24/Fedora-24-20160614.0/compose/Server/ppc64/iso/Fedora-Server-dvd-ppc64-24-1.1.iso
