I've been an Ubuntu user for several years, but I'm an end user not a developer. I was having problems with the old laptop I've been using so I decided to install 16.04 on my wife's old Lenovo PC, which had W7. I can run Ubuntu from the USB OK but when I tried to install it with the replace Windows option the installation process crashed.
Windows no longer boots, but this isn't a problem for me. I've attempted the installation several times but it keeps crashing with error
ubiquity crashed with signal 7 in FT_Stream_ReadFields()
.
I'd appreciate some help with this and will of course share any additional info that's needed to diagnose & solve the problem.
