The machine is a cheap Dell laptop that's about 10 years old. It's possible that an innocent change in the software triggered a latent hardware fault. > Perhaps you caught the mirror mid-update, does it still happen now? I did think of that. Minutes after the install failed, I confirmed that the mtimes on the Aarnet mirror were 10 hours old. I might have been mislead by timezones, and I'll try again tonight. Rodney
