I had already installed Ubuntu 18.04 LTS on /dev/sdb once, but the grub install failed, so I was reinstalling it, and so I chose "Erase disk and install 18.04 LTS over Ubuntu 18.04" or whatever it said on the screen. The implication was that the installer would auto-partition the 500GB disk and install Ubuntu into that newly partitioned disk. So I did not manually partition the disk. I intentionally let the installer overwrite the previous partitions on the disk.
During the installation, the installer failed to install the bootloader, so I tried various options from the dialog that was displayed, but they failed. So I opened a Terminal window and tried manually installing the bootloader, and that's when I got the "/cow" error. And perhaps that's when the installer crashed and sent this report. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1798810 Title: installer crashes after failing to install bootloader To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub-installer/+bug/1798810/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
