I appreciate your time, thank you+++

This is the message I receive upon startup... (screenshot)...

Everything comes to a halt.

Thanks!

yes same problem should we change the linux amd installation or wait so they fi it?

Okay, the issue was "/usr/src/realtek-rtl8814au-5.8.5.1~git20231211.866a910/dkms-make.sh", clearly.

It's been rectified via latest upgrade.

sudo apt-get clean && sudo apt-get update && sudo apt-get upgrade

reboot

Thank you, I appreciate your time!

i found this i think it can help https://www.kernel.org/ there is new release 6.9.4

it worked for me i fix it try this:

1st open terminal go to kali-tweaks
then network repos > clouflare > https then ok and when it finish use sudo apt-get update

@promote9612 I made your comments public as you were trying to talk to atdtphreaker. Be sure to uncheck the private box so others can see your messages

this works for me :- (sorry for a lengthy answer please read carefully)
! first backup your data and your essential drivers(backup is very important because in trouble and bad time may be you cannot able to do it if you use kali as dual boot or primary)
if you restart it and found error then you can:-
poweroff your machine (by button or unplug the cord )

strart your machine go to > advanced options > select kali 6.6.15 (your machine starts) >(now you can backup if not taken ).
try :- goto 'kali tweaks' then 'network repo.' then select 'mirrors:cloudflare' and 'protocol:HTTPS' and then 'apply' .
after above ,
open terminal and type 'sudo apt-get update' , 'sudo apt upgrade' then you get error like this:- bad exit status 2,sub procss /usr/bin/dpkg.... etc etc..
now figure out which package intruppt with linux headers and linux images
like here (look at raw output provided below) 'realtek-rtl88xxau' is cause of problem. (hey! may be your error different if yes then you need to remove that package ).
this is the error so we need to fully remove it
for remove :-
type command 'sudo su'
then 'locate package_name ( put stars before and after package_name and of course you need to replace package_name with your package which cause error)
!!! now before removing put some common sense and do not remove any other necessary or system pacakges (you can also copy file which you delete with their path so in any trouble you can easily revert the process)
now start copying the path of repos or packages and search it in your file manager ,, you can also use cli interface but gui is more simple.
after removing
'dpkg --configure -a' and 'apt upgrade' if error remains same reboot and try 'dpkg --configure -a' and 'apt upgrade'
if you cannot able to boot any error show then you can try:-
poweroff your machine (by button or unplug the cord )
strart your machine go to > advanced options > select kali 6.6.15 (your machine starts)
and try above commands with root privilage.
now error vanish.
and reboot normaly and type 'hostnamectl' (in terminal)
you greeted with
"Kernel: Linux 6.8.11-amd64" and other stuff

(raw output) for reference may be somethings different.:-

I also got the same errors, except that the log file was for rt8188fu wifi driver. I tried to purge the linux-headers-6.8.11-amd64 and related files through sudo apt --purge, but still failed. Then, using a method suggested on askubuntu, I tried aptitude and synaptic to delete the problem header files, and the synaptic one worked.

Hi,
I fix the issue by installing the following pack which was missing in my release

----> sudo apt-get install linux-headers-6.8.11-amd64

I had also an issue with dkms package ( apt realtek-rtl88xxau-dkms) i use the following commande the solve the issue

-->>sudo dkms --force install realtek-rtl88xxau/5.6.4.2\~git20240510.b44d288

and after that i use the commande

---> sudo dpkg --configure -a

IT Was really strange that DKMS was in conflict with the Headers for this specific driver pushed from git. Maybe a backdor lol

follow me on X : @F2po
