so I just uninstall KDE Neon because of a problem and tried to install it again but i got
integrity: Problem loading X.509 certificate -65 and the boot stuck/freeze. I thought it was KDE Neon error, but then I tried installing ubuntu 19.10 and got the same error. I even clean install my windows and delete other partitions, but it doesn't do anything, I keep getting the same error. What should I do ? Thanks in advance.
I've tried with 18.04 too and same result, strange, these iso files have no problem before.
I cleared my USB using RosaImageWriter, formatted it, and then I made my USB bootable using PowerISO, and choose install with safe graphics. The error still persists, but now I can boot Ubuntu 19.10 without getting stuck.
I get a black screen with this error:
