Driver not working after kernel upgrade #153

Closed dagohil closed 4 years ago

dagohil commented 4 years ago

Hello, After upgrading the kernel and therefore repeating the installation procedure, I got the following error message:

Dago@dago-MYBOOK-14:~/rtl8723bu$ sudo modprobe -v 8723bu insmod /lib/modules/5.0.0-31-generic/kernel/drivers/net/wireless/8723bu.ko modprobe: ERROR: could not insert '8723bu': Exec format error

Help appreciated

When these kinds of errors occur, you need to check the output of the dmesg command to get a better idea of the cause.

Thanks in advance for your assistance.

This is a very frequent msg and the only one related to 8723bu

8723bu: version magic '5.0.0-29-generic SMP mod_unload ' should be '5.0.0-31-generic SMP mod_unload '

Your kernel header version do not match that of the running kernel. The 'uname -r' will tell you the kernel version.

Yes I understand my new kernel is 5.0.0-31-generic and the header is 5.0.0-29. How do get them to match? Would be "sudo apt-get install linux-headers-generic" the right command. And if so what next? Sorry, but I dont know exactly what I am doing therefore I am a little bit cautious. :)

You should not be able to hurt anything by installing kernel headers; however, your distro's forum would be a better place to ask. My distro does not use apt!
