Hello! Yes, I do have the Sophos Antivirus software installed. However, your commands failed to work on my machine. Previously, I had done the same with a different command.
sudo systemctl stop sav-protect.service This usually does the trick (stops the antivirus), then I proceeded to your code of... sudo apt-get install -f ...which did nothing. I did try to update the linux image/kernel again... And these new packages were installed... frederick@frederickpina:~$ sudo apt-get upgrade linux-image-generic Reading package lists...

I then tried to reinstall the wifi drivers directly, via this method...

It feels like I'm making some marginal progress, but I also feel like I'm back to square one; and still am as mystified as ever regarding this technical issue. Does any of this help clarify the issue for you? Thanks again for your patience and support. I very much appreciate you. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1882194 Title: Intel Wireless 7265 [8086:095a] Subsystem [8086:5010] not probed after kernel packages upgrade failures To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1882194/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
