hi @xinliang - thanks for raising this bug, and for the info. I've got my way through to a grub build (I'm going to append some extra notes to your instructions) but, I'm unclear about where the:
$ sudo apt install ./*.deb is supposed to be applied - are you doing this on your pxe/tftp server? Or does this need to be in the image that is being netbooted? (or both?) If it's going on the pxe/tftp server, what files is it providing/replacing to resolve the bug (ie is it updating a bootx64.efi image)? As promised - a little extra detail on the build notes: $ git clone -b applied/ubuntu/focal-updates https://git.launchpad.net/ubuntu/+source/grub2 $ cd grub2 $ git cherry-pick a6838bbc6726ad624bd2b94991f690b8e9d23c69 # this will throw an error $ git remote add upstream https://git.savannah.gnu.org/git/grub.git $ git fetch upstream $ git cherry-pick a6838bbc6726ad624bd2b94991f690b8e9d23c69 $ dpkg-buildpackage -rfakeroot -b -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1892290 Title: PXE load Focal initrd.img-5.4.0-42-generic always timeout To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1892290/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
