Seeing the same. Seems like the permissions of the vmlinuz file in the kernel package are set 0600 instead of 0644. However, there seems to be a good reason for this: to prevent normal users reading the kernel image to work around ASLR. Fine, makes sense. But how to fix the permissions nicely for network booting? I think a simple workaround is in order. Create a file
/etc/kernel/postinst.d/chmod-vmlinuz with the contents #!/bin/sh -e chmod 0644 /boot/vmlinuz-* This should adjust the permissions of the kernel image automatically after it is installed. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1411330 Title: vmlinuz permissions To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1411330/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
