I just upgraded my laptop from 20.04 LTS to 20.10 yesterday.
Since 20.04, my wifi adapter RTL8822be didn’t work with default installed driver. But I could get it work with the method mentioned here https://github.com/mid-kid/r8822be.
With 20.10, again the wifi adapter doesn’t work with the default driver. However, above method doesn’t work any more. When i tried to run ./make, I got following error message. And the git repository has been discontinued.
./include/linux/vermagic.h:6:2: error: #error "This header can be included from kernel/module.c or *.mod.c only" 6 | #error "This header can be included from kernel/module.c or *.mod.c only" | ^~~~~ make: *** [scripts/Makefile.build:290: /home/maweimin/Downloads/r8822be/rtl8822be/trx.o] Error 1 make: *** [Makefile:1780: /home/maweimin/Downloads/r8822be] Error 2 make: Leaving directory '/usr/src/linux-headers-5.8.0-34-generic'
The git owner mentioned also to try the latest rtw888 driver at https://github.com/lwfinger/rtw88. But is says “IF YOU RUN UBUNTU, YOU CAN BE ASSURED THAT THE APIs HAVE CHANGED. NO, I WILL NOT MODIFY THE SOURCE FOR YOU. YOU ARE ON YOUR OWN!!!”.
I am not a good deep-user of Ubuntu/Lubuntu. Could anybody help me to get the wifi adapter work again with 20.10?
