Thank you for your suggestion to test the latest kernel. Unfortunately, I am having trouble booting using the suggested kernel (5.13-rc2).
I have downloaded the appropriate (I think) kernel packages from the link you provided: linux-modules-5.13.0-051300rc2-generic_5.13.0-051300rc2.202105162330_amd64.deb linux-image-unsigned-5.13.0-051300rc2-generic_5.13.0-051300rc2.202105162330_amd64.deb linux-headers-5.13.0-051300rc2-generic_5.13.0-051300rc2.202105162330_amd64.deb linux-headers-5.13.0-051300rc2_5.13.0-051300rc2.202105162330_all.deb I have verified the checksums, installed the packages, and configured them using dpkg --configure -a. When I try to boot using kernel 5.13-rc2, I receive the following errors: error: /boot/vmlinuz-5.13.0-051300rc2-generic has invalid signature. error: you need to load the kernel first Please advise. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1925843 Title: Linux 5.8.0-49+ fails to resume from suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1925843/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
