[Bug 1829331] Re: Grub regexp command does not work in secure boot mode
Hi, Try use the newest version. Secure Boot forbids loading any external modules thus command "regexp" on Ubuntu 19.04 does not work in the secure boot mode, but it works in the non-secure boot mode. regexp is in grub efi image (debian/build-efi-images). https://git.launchpad.net/ubuntu/+source/grub2/commit/?id=2235a503200aff73febb23484f2ec25e268f3d2e -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1829331 Title: Grub regexp command does not work in secure boot mode To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub-efi-amd64-signed/+bug/1829331/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1829331] Re: Grub regexp command does not work in secure boot mode
OK, for ubuntu-19.04-live-server-amd64.iso booting in secure boot mode, I found more commands are not working, at least including: lspci probe md5sum play sha1sum tr usb videoinfo While the following are working: ls cat echo help reboot I am wondering is this due to some purpose about security? Or?

[Bug 1829331] Re: Grub regexp command does not work in secure boot mode
I repeated the above steps for ubuntu-18.04.2-live-server-amd64.iso, and got the same result. The regexp command in the grub shell does not work in secure boot mode. However, it does work in non-secure boot mode. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1829331 Title: Grub regexp command does not work in secure boot mode To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub-efi-amd64-signed/+bug/1829331/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
