Same error for me on Fedora 32

Had to modify the script a bit but got it working on Linux Mint 19.3 (kernel 5.4.0-40-generic)

Thanks @ukn I've just tried your script on Fedora 32. I had to comment out line #43:

and it worked great. Enjoying my camera now!

Thanks Stono for this script. I ended up using it as the base for what I was trying to solve. I did try it like you instructed, but it wouldnt work on my machine. I have a 2015 MacBook Pro... I though about it a while and realized that the only time I need this to run is when I update the kernel, since this is when it kills the install. So I just changed the script to do the apt update then automatically just run your script and basically reinstall the driver immediately after the kernel update. Works perfectly. I put it on my page if your interested in seeing how I did it. Thank you for helping me get my camera running again.
