This is my very first installation of any Linux distribution. I have seen "pane is dead" questions and answers to them here, but I don't think they apply to me -- for one thing, I'm not using Kickstart (whatever it is). Also no virtual machine, no Parallels, etc... This is a clean install on a just bought disk (on a newly bought computer, really).
Here's what I did.
I downloaded 7.6.1810 DVD-ISO version from one of the mirrors given on the official CentOS site. Burned it to an USB stick using dd under Linux Mint. I made sure I burned it to USB as a whole (/dev/sdz), not to a partition (/dev/sdz1).
Now I plug the stick into the new computer. It is recognized and I'm greeted by "Install CentOS 7" screen. I choose "install", lines start running, most of which are ok-ed. Two lines are not ok-ed:
[ INFO ] dev-virtio\x2dports-com.redhat.spice.0.device is not active.
[ DEPEND ] Dependency failed for Activation socket for spice guest agent daemon.
Nevertheless, this run of lines successfully ends, after which I get "Starting installer, one moment..." and very quickly after that "Pane is dead".
When I alt-tab to log, I get the message saying something to the effect that log-file can't be found. And that's it.
GPU is Nvidia 2080.
USB stick is 6 months old. I've used it successfully as a boot drive for Win 10. Today I formatted it and burned with centos using dd. Now when I plug it into a win-computer, windows doesn't recognize it -- it's not on the list of discs. If I go to disk management, it's there, it has one 9 mb partition called "Anaconda" and 14.59 gbs' worth of unallocated disk space (it's a 16 gb stick).
EDIT: Turned out it was the dying USB stick.
