I suspect you have somehow missed the key enrollment step, as show in https://bugs.launchpad.net/ubuntu/+source/rtl8821ce/+bug/1847283/+attachment/5295739/+files/photo_2019-10-09_12-40-35.jpg
Can you turn on secure boot again, then run: sudo mokutil --import /var/lib/shim-signed/mok/MOK.der Follow the instructions on screen. When you reboot again, just before loading GRUB, shim will show a blue screen, select “Enroll MOK” and follow the menus to finish the enrolling process. You will be asked for the password you typed in earlier when running mokutil. After that, see if rtl8821ce is shown in lsmod. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1847283 Title: Not work: "01:00.0 Network controller: Realtek Semiconductor Co., Ltd.
