This bug seems quite similar to the one I reported: Ubuntu 20.04 LTS Fails to boot on Lenovo Flex 3-1480 laptop: Bug #1925710
As my bug explains, my 2015 Flex 3-1480 has a similar boot issue problem, though my 2019 Acer E15 Aspire E5-576 boots just fine. Anyone think these are the same bug? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1925010 Title: shim-signed 15.4 does not boot on EFI 1.10 systems To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/shim/+bug/1925010/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
