For those who are concerned....

Last week I downloaded an I386 image for Jessie Netinstall.

After using it on a fresh machine, I learned _after_ reboot that
I could not do 'apt-get update' successfully.

The archives as found in 'sources.list' did not (longer)
exist............. !!

Luckily I could copy them from my other Devuan Jessie machine and
after that I could update and install with no problem.

Others may experience these problems too and I don't know
if it is limited to Jessie Netinstall only.
