calamares has hung, 20.04 qa-test install

[Chris Guiver]

Lubuntu 20.04 LTS daily (2020-04-05) ISO

install on

hp dc7700 (c2d-e6320, 5gb, nvidia quadro nvs 290)
testcase: Custom partitioning on xfs

froze during Manual Partitioning.

-- layout
Partition layout was (comment #5)

/sda1 FAT32
/sda2 extended
  /sda5 ext4

-- what I believe I did

DELETE partition SDA2 first (ie. extended partition)

-- what I hoped would happen

Hoped (I guess) it would delete all partitions within extended; alas it freezes calamares. (note: I'm adding this after the event, in exploration this is how I can re-create freeze)

To not have it freeze, delete sda5 first, then sda2 can be deleted cleanly (expected behavior anyway)

-- Original text for bug report

I hadn't started creating a partition, was in the process of deleting prior install partitions when it just hung/stopped still. It was left a few minutes, before I opened a terminal (refer screengrab and you can see the terminal being dragged to the lower screen so I could explore).

Nothing found in /var/crash/
I didn't see anything useful in `dmesg` nor `journalctl`

~/.cache/calamares/sesion.log attached
screengrab showing frozen calamares (top screen) and me dragging terminal down to lower screen is also somewhat evident..

screengrab - shows only hung calamares on top screen, and me draging terminal to lower screen where it was maximized, machine operation is good, calamares however is stopped.

Detail from `journalctl`
I opted to paste instead of whole file, I searched for /alamar/ and this is from that point to end of file..

Partition layout was

/sda1 FAT32
/sda2 extended
  /sda5 ext4

In play after test, I could re-create this
DELETE partition SDA2 first (ie. extended partition.

Hope would be it would delete all partitions within extended; alas it freezes

To not have it freeze, delete sda5 first, then sda2 can be deleted cleanly.

[Chris Guiver (guiverc)]

exploration later in order to re-create freeze
I'd entered calamares with `sudo -E calamares -d`
