Running OSMC successfully for years on Raspi 2 with touchscreen and hifiberry.
After the last upgrade and reboot, wifi did not come up and therefore OSMC fails to start, showing a white frownie symbol on black background.
connmanctl shows no wifi technology.
Entering “wpa_supplicant” in a root shell gives: wpa_supplicant: error while loading shared libraries: libnl-3.so.200: Wrong ELF class: ELFCLASS64
uname -a gives Linux osmc-pi 4.14.78-4-osmc #1 SMP PREEMPT Wed Dec 12 17:58:11 UTC 2018 arm7l GNU/Linux
So it appears that the lib has to be - wrongly - replaced with a 64 bit binary on my 32 bit system. How can I find and put the correct library?
Could it be you added a wrong package repository? Check your sources.list.
Also if you can create a internet connection via wireless upload logs with grab-logs -A
