Hi,
 
I am start using pine64-LTS board and currently installing new OS in SD card successfully. Please check below result of "uname -a" according to my board. 
"Linux pine64so 5.10.34-sunxi64 #21.05.1 SMP Fri May 7 15:50"19 UTC 2021 aarch64 GNU/Linux"
 
Now, I want to modify or add some features through kernel. Please guide me how to get kernel source and rebuild process.

Hello,

I have started compiling the kernel for pine64 board as per above suggested link by the following command.

$ ./compile.sh CLEAN_LEVEL="make,debs,oldcache,cache" NO_APT_CACHER=yes USE_TORRENT=no

I have used "NO_APT_CACHER=yes" to avoid error from proxy settings. Moreover, "USE_TORRENT=no" to avoid fetch URL failed error. However, again I have encountered an error which can be seen in the screenshot attached. I don't exactly know why this error has occurred.

Please guide me to compile it successfully.
