bug#50004: got exception while creating partitions

[John Kehayias]

Hi,

Thanks for filing this, I actually hit I think the same error when using the 
installer a week or 2 ago (built fresh from the main branch, not 1.3.0 which I 
found even flakier). This was on a nvme drive, also trying to just do the 
default ext4 partitions.

In general, it seems the partitioner is brittle: it didn't like some partially 
created partitions from a previous run, once made /boot an ext4 partition 
(rather than fat32), didn't like my messing with manual configuration.

In the end, I made sure to start with a clean (no partitions drive) and then it 
worked. I wish I had more detailed info, but for obvious reasons can't 
reproduce it now. I think I have some photos available, but looked like the 
same error I remember seeing.

Oh, and when there is a problem with partitions the installer kicks you back to 
the very beginning, which makes for a more tedious process in figuring out how 
to make it work.

Hope this is helpful!

John
