isoimagewriter in OpenMandriva Lx

I am user knowledge level. I do not know why this occurs, if is the isoimagewriter or something within OpenMandriva's system packages. But we would like to have this tool working. 

Also the previous version isoimagewriter-0.8-0.20210514.1 did work OK. The only issue then was that the verify checksum utility does not work on OM Lx .isos but that is another, less important, issue.

I will do or provide whatever I can to help find the cause of this. I can get in touch with OM devs if needed.

OM's git stuff: https://github.com/OpenMandrivaAssociation/isoimagewriter  >>> obviously OM is doing these packages as git snapshots.

OpenMandriva issue report: https://github.com/OpenMandrivaAssociation/distribution/issues/2750

This is a confirmed issue at OpenMandriva.

Looks like I missed some info in my report:


That isoimagewriter copies the .iso image to the usb flash drive.

I will admit I wished I knew if this was really an issue with isoimagewriter and not something with some OM Lx system package? Or something like how OM Lx mounts or does not mount flash drives when they are plugged in? I just do not know. But I do know the previous v. OpenMandriva had did work OK.

For what it's worth, I got a very similar error in Kubuntu 23.04 - I had to umount /dev/sdb<#>, then it worked

Add a mee too.

I'm using the tip of Master 5011295430dc929742fcdb6d270093e9d1ca78f7, and I encountered "The last block was not fully written (-1 of 1,048,576)". I don't think the first block was written because I get the error immediately.

From the other bug reporter, I found https://invent.kde.org/utilities/isoimagewriter/-/issues/1, which brought me here.

My machine is Kubuntu 22.04.3, x86_64, fully patched. Plasmashell version 5.24.7.

I can provide SSH access to the machine, if needed.

I'm also getting the "-1 of ..." version of the "The last block was not fully written" error immediately after attempting to write an ISO when using the Flatpak build on Kubuntu Linux 20.04 LTS.

Here's the version information:
