Hi community,
I am new to Ubuntu and to linux . I searched on this forum and other forums before posting this question. Some similar questions use very technical linux language in the replies, which I don't quite understand.
I have ubuntu 18.10, it came with kernel 4.18.0.10.11 (wifi works, touchscreen doesn't work), ubuntu self updated to 4.18.0.13.14, I noticed an improvement on performance (runs smoother, apps seem to open faster), but wifi stopped working, and touchscreen issue not fixed. I uninstalled 4.18.0.13.14 and currently using 4.18.0.10.11.
I tried updating to 4.20.3 using ukuu, but it is not booting up and the following error comes up when it is trying to boot up:
"
error: /boot/vmlinuz-4.20.3-042003-generoc has invalid signature
error: you need to load the kernel first.
Press any key to continue..._
"
I have tried enabling / disabling secure boot on bios with no luck.
I would like to update to newer kernels to see if the touchscreen issue is fixed, plus improving performance while keeping the wifi working. Any newer kernel tried using ukuu gives me the same error. I have also tried manual update with the same results.
Any suggestions or help will be appreciated. Thank you in advance.
