lubuntu install (bionic daily) halts

Since sdb5 i'm convinced is thumb-drive or install media, it was created with

`dus` (or mkusb)

This was the second install from thumb-drive since written, first was entire-disk install, second being install-alongside. Same order as was done last time... (last time was I think day web site issue was discovered by sil2100/Lukasz; though message only appeared during install alongside if I recall correctly; NOT the initial entire disk & NOT later manual.partitioning to confirm sil2100's fix)

I just had a repeat of this issue,
- identical box
- no 'OK' box, the window is just sitting there
- title isn't even visible in window & install questions haven't started...
- no crash files in /var/crash

I'm suspicious this issue isn't with ubiquity itself (assuming today is the same issue again), but the box itself.
In `dmesg` I see the following

Earlier in `dmesg` is

which I think relates to the SDB message mentioned...
No squashfs errors found in `dmesg` & validation (check disc for defects) step was manually performed.

This has now occurred (same box as initial report) using the Xubunu 18.04.5 install

hp dx6120mt (mini-tower, pentium 4 dual core, 3gb, winfast clone of nvidia 7600gt)

an error has appeared
--
Failed to create a file system
The ext4 file system creation in partition #5 of SCSI5 (0,0,0) (sdb) failed.

On Lubuntu installs, SDB was the installation media, sda being the hdd. I noted this error on Lubuntu 18.04.5 installs though too (it's mentioned in https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1890872 but the bug was reported about what I considered another issue; will this install now lock up which is what I filed that bug about.....)

it's just stopped still.. ctrl+alt+T opened a terminal and I see the same messages I reported in https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1890872 so it's likely that issue, be it related to this box (identical box to other report) OR something in code this old cpu don't like...

The slideshow hasn't moved in 50 minutes, and no messages have appeared. I `ubuntu-bug ubiquity` and selected this bug again.. in hopes more detail would be added (I considered new bug & marking duplicate).. but I'm getting tired.

Xubuntu install-alongside on dx6120 `dmesg`

Xubuntu install-alongisde on dx6120 `journalctl`

on Xubuntu install, SDA refers to hdd, SDB (and error) refers to install media
