> Ubuntu 21.04 is the first release media that includes > 15+1552672080.a4a1fbe-0ubuntu2 Sorry, I meant to write Ubuntu 20.10. The following command on Ubuntu 20.10 shows no problems with the text console: virt-install \ --name vm2 \ --vcpus 4 \ --ram 8192 \ --graphics vnc \ --video vga \ --network network=default,mac=52:54:00:00:00:02 \ --cdrom=devel/iso/ubuntu-20.04-live-server-amd64.iso --check path_in_use=off \ --disk=hda.qcow2 \ --boot=loader=/usr/share/OVMF/OVMF_CODE_4M.secboot.fd,loader_ro=yes,loader_type=pflash,nvram_template=/usr/share/OVMF/OVMF_VARS_4M.ms.fd \ --machine q35 Also looks fine with ubuntu-18.04.5-live-server-amd64.iso. So I don't see anything to suggest this is a problem with a "vanilla" install process. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1841202 Title: during install kernel console garbled when secureboot enabled To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/shim-signed/+bug/1841202/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

> The version of shim as reported by 'apt-cache show shim' is: > Architecture: amd64 > Version: 13-0ubuntu2 This is a VERY old version of shim, and not the current version present in bionic. It is also definitely NOT the version that is used by the Ubuntu 18.04.2 release media (the version that was current in bionic at the time of that media's release was 15+1533136590.3beb971-0ubuntu1, that is the same version that was current in bionic at the time of 18.04.5's release, and the current version - not included in any release media - is 15+1552672080.a4a1fbe-0ubuntu2). The regular point release cycle for 18.04 LTS has concluded, so if this bug is fixed in 15+1552672080.a4a1fbe-0ubuntu2 but not in 15+1533136590.3beb971-0ubuntu1, you would need to use release media for a newer release in any case. (Ubuntu 21.04 is the first release media that includes 15+1552672080.a4a1fbe-0ubuntu2; Ubuntu 20.04.2, to be released next week, will also have it.) > A rather vanilla qemu/kvm guest: > [...] > --cdrom=/root/bug29812426/work/isos/UefiShell.iso --check > path_in_use=off \ > [...] This doesn't look very "vanilla" to me given that you are booting an image called "UefiShell.iso", not booting the Ubuntu install media.

Re: [Bug 1841202] Re: during install kernel console garbled when secureboot enabled
Terry, I am unable to make it through the install process with secureboot enabled. I did install bionic with non secureboot, then enabled secureboot via EnrollDefaultKeys, and upon the subsequent reboot, the text console was fine, quite readable. The version of shim as reported by 'apt-cache show shim' is: Architecture: amd64 Version: 13-0ubuntu2 This is what shows after installing without secureboot enabled; so I'm not sure if the install process has updated shim from what is on the .iso. The problem really only appears to manifest upon installation. I don't have the know-how to swap out the shim on a bionic .iso.
