Chris Guiver's assessment is correct. I'm embarrassed that I did not run an MD5 check before attempting to install. It did not occur to me that the ISO might be bad until quite a while after the first occurrence of the error.
I think it is worth pointing out that I was able to create a bootable USB drive, boot from that drive and use Ubuntu from that drive. It was not until attempting to install Ubuntu that the corruption became evident. So, it was non-intuitive that the ISO might be bad. After all, I was running on a drive created from the ISO. I have enough experience on linux, Ubuntu and SWQA that I should have caught this sooner than I did. However, as the Ubuntu user base expands and as Ubuntu strives to compete with Windows and Mac OSX, this issue is going to cause a lot of frustration for less experienced users. My suggestion is that Ubuntu Startup Creator run an MD5 check on the ISO before proceeding with the creation of the USB drive. Whether it offers a warning or simply refuses to create the bootable USB drive is for the UX geeks to decide. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1868348 Title: Clean install, installer crashed after disk partitioning set up To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1868348/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
