Just did an install of 18.04 i386 and it went very well. The only
glitch I have seen so far:
I usually do a manual config of disk partitions. So I selected
home, root, and boot partitions and all of that went well with one
exception. I first decided not to format the /home partition and
didn't flag it to format in the manual partition selection. But
when I came out of that, I clicked on the 'format' box for /home and
the installer crashed.
Not a biggie in my view because I RARELY get through an install
without at least one installer crash... I think that is a big
weakpoint of *buntu installs.
The rest of the install is going great... Haven't found any other
problems but will keep at it.
