[Bug]: install.sh unable to determine kernel version

[mkatliar]

Describe the bug

To Reproduce
Steps to reproduce the behavior:

sudo ./install.sh

outputs the message

WARNING Your loaded kernel version is 5.15.0
 Not matching the updated version .
 Kernel was updated, but new kernel was not loaded yet
 Please reboot your machine AND THEN run this script again

and does not start building the driver.
Same error after rebooting.

The output "Not matching the updated version ." (empty version string) suggests that the script is unable to determine the kernel version (get_kernel_version()).

Expected behavior

Drive builds and installs.

• Device: Raspberry Pi 2
• OS: Ubuntu 22.04.1 LTS 5.15.0-1021-raspi

It did work with v6.0 branch from your fork, thank you!

Shouldn't the changes from that branch be merged to the master of the main repo?

[HinTak]

This is probably an FAQ - the main reason it being an on-going process (to update for current kernel) so there is no fixed point for a pul; the other is that, while I like to keep it up to date as a way of following kernel development, and I like to do with well, clearly and documented properly why each individual change happens and at what kernel version (unlike some of the whole-sale change style upstream does), I don't actually test the change on real hardware. My Pi box is not operating for other reasons atm.

Thank you for the explanation. I close the issue.
