Finally I was able to successfully install with secure boot enable. Steps: 1. Configure debconf to use readline instead of dialog 'dpkg-reconfigure debconf' 2. Install package 'apt install xtables-addons-common' 3. After the secure boot signing key is generated, system asks to input a password: -- Enter a password for Secure Boot. It will be asked again after a reboot. -- Type password. If typed password is too short or too long, the system will ask again to type a password.
Press enter and type once again the password. -- Enter the same password again to verify you have typed it correctly. -- 4. Reboot 5. Enrool MOK and reboot. 6. Done! This is a workaround, xtables-addons-common installation should also work using dialog prompt. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1775231 Title: (uefi, ubuntu server 18.04) failed to install xtables-addons-common when secure boot is enable To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/shim-signed/+bug/1775231/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
