Ok I have gone nuts trying to figure this out, and I'm just about ready to just re-install the OS. (Fedora 29) I have been using Fedora since like....version 12, and have experienced all kinds of issues but this one baffles me. So:
I had updated from fc26 to fc27 successfully, but I have noticed that since upgrading from 27 to 28 that the kernel versions while they have gone up (e.g. from 3.12.203 >> 3.12.207 and these numbers I use are for example only!) I notice that the "fc" number has remained the same (in other words the "fc27" bit of the kernel name!) I have tried everything I have found online from trying to upgrade the kernel through the Terminal to trying to download, install, and compile a newer kernel version and no matter what I've tried that part remains the same. So my last attempt/effort will be a transfer of all my data and a complete re-install of F29. But it would be nice to know what might have caused this...in case it happens again!
