lubuntu 18.04-2 installation crashes

[Jonathan Wachtel]

Lubuntu 18.04 will not install on my computer.
1. Gigabyte GA-VM900M motherboard
2. Intel 3 MHz P4 single core cpu
3. 2.5 GB of DDR2 ram
4. Nvidia Geforce FX5500 video board w/256 MB memory
5. 10 GB hard disc drive
This system worked well with Lubuntu 14.04 (upgraded on-line
to Lubuntu 14.04.6), although there were intermittent crashes
of Firefox on certain internet websites.
