Comment 12 for bug 1761377

I can confirm on a Lenovo T440. Attempted to overwrite an old (30GB) 16.04 install on / (sda1 for me) while leaving the separate user partition (210GB on sda5). The error popped-up as described by previous commenters. I attempted to rename a new user (different than my existing account both times) but the error persisted. I opted to continue to see what would happen. Currently, I am at the "install" graphic page while my cursor has turned into a perpetual spinning ball of sadness.
