As expected the output was identical as it's essentially just a fancy USB port on the end of a metre lead.It seems then the system recognises it being plugged in, and identifies it correctly. It just won't use the driver to load it.This appears to be /why/..

Mint wanted to update the kernel and headers etc to 4.15.0-96-generic, and seemed to do it, but I spotted this in the middle..Processing triggers for linux-image-4.15.0-96-generic (4.15.0-96.97) ... /etc/kernel/postinst.d/dkms: * dkms: running auto installation service for kernel 4.15.0-96-generic Kernel preparation unnecessary for this kernel.

Bad return status for module build on kernel: 4.15.0-96-generic (x86_64) Consult /var/lib/dkms/rtl8814AU/4.3.21/build/make.log for more information....done. This is what make.log said: cc1: some warnings being treated as errorsscripts/Makefile.build:288: recipe for target '/var/lib/dkms/rtl8814AU/4.3.21/build/core/rtw_cmd.o' failed make[2]: *** [/var/lib/dkms/rtl8814AU/4.3.21/build/core/rtw_cmd.o] Error 1 Makefile:1655: recipe for target '_module_/var/lib/dkms/rtl8814AU/4.3.21/build' failedmake[1]: *** [_module_/var/lib/dkms/rtl8814AU/4.3.21/build] Error 2 make[1]: Leaving directory '/usr/src/linux-headers-5.3.0-45-generic' Makefile:1699: recipe for target 'modules' failed make: *** [modules] Error 2There are still all kinds of things not right here, but no reason to panic and do a reinstall. In no particular order:The dmesg "tainting kernel" message isn't what you think it is - read it more carefully. The module is tainted because it's out of tree and you built it yourself without properly signing it, hence "tainted". The kernel is complaining about _that_: note in the next lines it clearly tells you it's then loaded it anyway and registered the interface. You would have been better served by googling "tainted module" so you knew what that was first and then doing "lsmod | grep 8812au" to see if it was _actually_loaded instead of jumping to random conclusions about what you _think_ it's telling you...Another case of "read carefully what the computer is telling you" comes with the dkms build:
I thought about this last night, and I wondered why Mint's Update Manager listed kernels older than the one I had running. I /think/ what may be happening is that the Update Manager keeps a record of what /it/ has installed and offers updates based on /that/, not what is actually installed.Error! Bad return status for module build on kernel: 4.15.0-96-genericQuoth the dkms error - note the kernel version 4.15.0-96-generic. However when you then show the log spot the difference:> make[1]: *** [_module_/var/lib/dkms/rtl8814AU/4.3.21/build] Error 2 > make[1]: Leaving directory '/usr/src/linux-headers-5.3.0-45-generic'Note the linux-header version "5.3.0-45". What the hell is going on here? I genuinely have no idea how your Mint box is trying to compile for 4.15.0-96 against headers 5.3.0-45 (it's obviously not going to work).
My apologies. Yes I followed your instructions and got everything matching, kernel, headers etc. uname gives 5.3.0-46-generic.I'm also guessing that you may have followed the commands I gave you but didn't mention that you've done so. Otherwise linux-headers-5.3.0-45-generic has somehow snuck onto your system without you knowing. Do you have the matching kernel to go with it? I'm presuming not otherwise your PC should have booted up from it.
sudo apt install linux-image-5.3.0-46-generic linux-headers-5.3.0-46 linux-headers-5.3.0-46-generic --reinstall -yAs above I did that when you advised me to. I think what happened is I didn't spot when Thunderbird replied from the wrong address, so I intended to confirm I had done it but it didn't get to the list.
In a nutshell I am currently running thw kernel you advised above.
