hello Steve, basically i have a lenovo B575 laptop which had wind7 OS on it. and later I decided to upgrade to ubuntu for my studying purposes. so I did that and tried installing ubuntu 19.10 through USB drive ubuntu image on it. during installation i choose to let ubuntu decide about my partitions by deleting everything in my laptop and install a fresh new os UBUNTU 19.10. but unfortunately installation failed during installing the GRUB package and system asked me to restart. then i restarted it. which led me to GRUB black screen. after that i tried googling a lot and used boot-repair several time. and finally i restarted my PC and i see ubuntu OS came up and i logged into it by entering my password. but in start-up I received those error that mentioned in this bug-ticket:
[ package grub-efi-amd64-signed 1.128.2+2.04-1ubuntu12.2 failed to install/upgrade: installed grub-efi-amd64-signed package post- installation script subprocess returned error exit status 1 ] please help me out what to do; as i'm very new to ubuntu. thank you! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1868228 Title: package grub-efi-amd64-signed 1.128.2+2.04-1ubuntu12.2 failed to install/upgrade: installed grub-efi-amd64-signed package post- installation script subprocess returned error exit status 1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2-signed/+bug/1868228/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
