I've enabled a secure boot for my Ubuntu 20.04 as it was a mandatory step when installing a kernel module the (apt install v4l2loopback-dkms v4l2loopback-utils). All went automatically and that's fine. The secure boot is working.
But the generated key (the one used to "sing my boot") will expiry in a year.
Should I worry? Does it prevent my Ubuntu from booting after that date?
