Another iso https://archive.org/details/what-if-jun-27-2014-prototype/

Hello,

I will try to investigate, but it would be easier if you had a smaller iso to test with.

Could you test this command to mount your iso:

```
udisksctl loop-setup -f myisofile.iso
```

Error when loading the second ISO:

Loading the archive ‘/home/justin/Downloads/what-if-jun-27-2014-prototype/What if (Jun 27, 2014 15.44.07PM aka Life is Strange).iso’ failed with the following error:
Archive corrupted or insufficient permissions.

When opening from terminal:
ark.kerfuffle: Could not detect mimetype from content. Using extension-based mimetype: "application/x-cd-image"
ark.kerfuffle: Could not detect mimetype from content. Using extension-based mimetype: "application/x-cd-image"
ark.libarchive: Could not open the archive: Lzma library error: Corrupted input data

Permissions on ISO -rw-rw-r--

Sorry those comments were meant for the Ark bug about the same ISOs.

I've just used the "Mount Unmount ISO" addon service by "pulsar-ai" to mount and unmount the second ISO and I can browse the contents of the disc.

So I tested the iso from the link and the only problem is that the mimetype of the iso is not recognized.
The downloaded iso file uses the `.mdf` extension which seems to not be recognized as an x-cd-image file.
If I rename the file with a `.iso` extension, everything works as intended.

So the problem is not with the plugin itself but with the handling of the mimetype of the file.

I've identified that i cannot mount these iso's because they was stored in ntfs partition, mounting from ext4 works fine.

Okay, I have no idea why this is the case.
I hope someone more experimented can comment on this issue.

So, I actually tried to mount an iso from a USB key formatted with a NTFS partition.

What I have found is that the iso is actually correctly mounted (I was able to explore the iso by going to /run/media/username/myiso) but it did not appear in the dolphin sidebar.

Therefore, I think this is a problem with Dolphin itself.

@Kwon: could be an issue with solid. Does "solid-hardware5 list" show it?

I have the same problem on Arch Linux.
In the attached screen recording, I can't mount two DVD-video ISO images created with K3b.

Mounting with udisksctl gives me this output (ISOs are still not visible in Places panel of Dolphin after
this command):
$udisksctl loop-setup -f <my ISO>
Mapped file <my ISO> as /dev/loopX.

Hello,

Does this bug still happen ?

Also, does the iso appear if you restart dolphin ?

Despite sometimes I need to restart Dolphin to make the mounted ISO visible in the Places panel, I'm unable to reproduce this bug. Tested on Arch Linux with Dolphin 22.08 RC and on neon unstable.

Looks similar to https://bugs.kde.org/show_bug.cgi?id=443125

I tried mounting both iso's linked by me in latest fedora kde vm, they mounted fine, and without restarting dolphin, so i suppose it's fixed now. Bug can be closed.

There is no problem in mounting ISOs. All are mounted perfectly fine in media folder.
There is problem with displaying mounted ISOs in Dolphin.
Bug persist's even here with more interesting results while mounting in Dolphin:
