xubuntu bionic daily; error restoring applications ; on a formatted partition?

[Chris Guiver]

Xubuntu 18.04.5 daily QA-test install on
dell [optiplex] 755 (c2d-e8300, 8gb, amd/ati radeon rv610/radeon hd2400 pro/xt)

I removed the sda5 (second) partition, then used the free space to create new partition; installer indicated it'll be sda2 now..

Error appearing during installation

Error restoring installed applications
An error occurred while restoring previously-installed applications.
The installation will continue, but you may have to manually reinstall
some applications after the computer reboots.

This would fit maybe if I hadn't formatted the partition. I deleted and then re-created the partition that it was installing to, so this issue shouldn't exist I believe.

The install worked perfectly except for this issue, so it's a minor issue.

I erased & re-created the single partition on this system, so didn't expect this error. I don't expect any restoration of packages to occur, but even if it did - my install was from the same image with no packages added (unless downloaded & installed during install itself, which could have been done again).

The installer then exited??? no reboot message at all??? !!!

I later worked out entering LIVE mode occurs b/c of error.

In the Kubuntu installer, if you delete partition, then create the same EXT4 partition using the same space, it'll default to NO-FORMAT and thus re-use the prior partition. This is why the message occurred.

However the packages present were only ones using a Kubuntu install process as per testcase, nothing extra, so this error I don't believe should occur. Even if installer download & installed extra packages, why can't it download & install them again this time, I've not done any no-internet QA-installs last two days.
