mount img with dolphin

I found a command line method that works as well. I didn't try Furius ISO as I didn't want to install a program just to mount .IMG files and I also didn't want to run any GTK software on my Qt/KDE system.

First you need add the .img file if it is a full disk like mine was.

sudo losetup -f -P imageFileName.img

Then you need to figure out what loop back device it was mounted as.

lsblk -f

After you figure out which partition you want to mount specifically you use this command. The /dev/loop0p7 is going to be your partition name.

sudo mount /dev/loop0p7 /mnt/

I am not sure if this information changes, but you could easily put this into a script if you needed to.

I should also add that once you do this, you get an entry in Dolphin.

Dolphin context menu services

One would expect this to be achieved from the context menu with a default or custom "Service". Those are Dolphin scripts that can be downloaded (Settings - Configure dolphin - Services - Download new services, search "mount" or "iso"; they are .desktop files tha should go to ~/.local/share/kservices5/ServiceMenus or usr/share/kservices5/ServiceMenus).

That seem very promising but most of those do not work. Many are outdated, the newest ones are not the best rated. Luckily, there are exceptions:

KDE-Services (the best rated at the moment I'm writing is also up-to-date and works in Plasma 5.8): it seem it cannot be installed from the Dolphin-Services button; instead, it can be downloaded as tar.bz2 archive from here, unpacked and, by opening a terminal in the resulting folder, it can be installed by running the command sudo make install. This is a collection of services, installed at system level in /usr/share/kservices5/ServiceMenus/, and also scripts in usr/share/applications.

It will mount the image in a newly created folder inside the same directory as the image; there is also the unmount option that works just fine (as the image is not listed in the Dolphin Devices list, this is not affected by the problem mentioned below for the separate applications).

The only problem I see here is the huge number of services that it installs in this way. It comes with a plethora of tools that may not be needed (they can be hidden if un-checked in Settings - Configure dolphin - Services, but their upper menus remain visible. To fix that, one could carefully remove the unwanted service files from /usr/share/kservices5/ServiceMenus).

It is also better to save the downloaded package in case you want to completely uninstall this tool by unpacking it, opening a terminal in the resulting folder and doing sudo make uninstall.

I have posted a simple context menu service to mount/unmount (HERE) based on the above one, in case one wants to have just the iso mount/unmount option above.

See description at link on how this simple service was created.

Or - to create it manually:

kate ~/bin/iso_manager-mount-image.sh 

With this content (pasting this here in order to avoid the need of installing KDE-Services or uploading the script):

Considering separate programs:

As the question is labeled under KDE/Kubuntu, I will try to mention only programs that are as KDE/Qt-friendly as possible, that is, which bring few non-kde dependencies.

Acetoneiso comes in Plasma 5 with only three supplementary packages: fuseiso and other two that are qt-based.

sudo apt install acetoneiso

To see it in Dolphin you have to add the program to the file properties of the iso file.

Then, it can be found in Dolphin under the Open with option:

That will mount the image, open it in Dolphin, and also open the Acetineiso window, where you can find the Unmount option.

gnome-disk-utility, in spite of the name comes without non-kde dependencies in Plasma 5.8 (in fact no dependencies at all), and it includes (beside gnome-disks, also called "Disks", default in Ubuntu) a tool called gnome-disk-image-mounter.

sudo apt install gnome-disk-utility

It then can be found in Dolphin under the Open with option.

At this point the image is not automatically opened in Dolphin, but is listed in the Dolphin's left panel under Devices.

This program seems to lack an option to unmount the image: that can be done from the devices list in Dolphin.

There seem to be a sort of Dolphin bug here though: once unmounted, whether from the Acetoneiso button or from the Dolphin devices list, the list entry will remain there (called 'Loop device' in the case of gnome-disks) which, if selected, will again mount the image. That entry will stay there until system restart (logout is not enough).

These programs could be used with a service menu also (but they both lack an unmount command).

For example, instead of the above one could use this with Acetoneiso:

kate ~/.local/share/kservices5/ServiceMenus/acetoneiso-mount-iso.desktop 

with the content:

[Desktop Entry]
Type=Service
ServiceTypes=KonqPopupMenu/Plugin
MimeType=application/x-cd-image
Actions=mount
X-KDE-Priority=TopLevel
X-KDE-StartupNotify=false
Icon=application-x-cd-image
X-KDE-Menu=Mount with Acetoneiso



[Desktop Action mount]
Name=Mount with Acetoneiso
Icon=Acetino2
Exec=acetoneiso %f

Furious ISO Mount (furiusisomount) wants to add a significant number of gnome packages compared to the above, including Nautilus, therefore I leave it aside in this answer.

The following additional packages will be installed:
  fuseiso9660 gnome-desktop3-data libexempi3 libgail-3-0 libgnome-desktop-3-12 libmediaart-2.0-0 libnautilus-extension1a libtracker-sparql-1.0-0
  libunity-protocol-private0 libunity-scopes-json-def-desktop libunity9 libzeitgeist-2.0-0 nautilus nautilus-data

Furius ISO Mount allows you to mount easily want you want.

I hope it will be useful.
