Get ok message when installing deb with apt in terminal (from context menu or click)

Question

I find apt in terminal as the best way to install a program from a deb package. As I prefer it to other gui tools, I want that in the context menu for deb files or as a launcher among applications in order to install the deb by executing it with (double) click.

In Kubuntu with Dolphin I have created a service menu to create that context menu, also a desktop file in ~/.local/share/applications to achieve the same action by executing the deb file.

The file ~/.local/share/kservices5/ServiceMenus/install-deb.desktop:

[Desktop Entry]

Actions=install
Icon=dialog-information
MimeType=application/vnd.debian.binary-package
ServiceTypes=KonqPopupMenu/Plugin
Type=Service
X-KDE-Priority=TopLevel


[Desktop Action install]
Exec=konsole --hold -e sudo apt install %f
Icon=dialog-information
Name=Install

The file ~/.local/share/applications/install_deb_term.desktop:

[Desktop Entry]
Name=Install in terminal with apt
Comment=Install deb files in terminal with apt
Exec=konsole --hold -e sudo apt install %f
Icon=gdebi
Terminal=false
Type=Application
StartupNotify=true
Categories=GNOME;GTK;Settings;HardwareSettings;X-GNOME-Settings-Panel;System;

---

All is well, excepting the fact that without the --hold argument in konsole the terminal closes to quickly (which is not good in case of error), while with that argument the terminal stays open with a rather inconclusive message like so:

 Setting up <whatever_program> ...

which is not what I expect if the installation went fine.

---

Can I get some "OK" message at the end of the installation process with apt? Maybe through a script containing the apt command?

---

Update:

Following comments by @DKBose: modifying ~/.bashrc as in this answer I get the desired notification popup with a command in terminal like

sudo apt install /path/to/deb; alert

but not with the line

Exec=konsole --hold -e sudo apt install %f; alert

in the files above (installation works, but no popup).

For the alert argument to work at all, installation of libnotify-bin was needed.

This answer addresses the issue of installing a .deb file using apt install via a service menu in Kubuntu 18.04.

First, we download a small .deb, gcolor2 which is not in the bionic repos, using the link provided by N0rbert here.

~/Downloads $ wget http://mirrors.kernel.org/ubuntu/pool/universe/g/gcolor2/gcolor2_0.4-2.1ubuntu1_amd64.deb

Next, based on the service menu .desktop file in the question and comments by muru, the following service menu .desktop file, ~/.local/share/kservices5/ServiceMenus/install-deb.desktop was constructed:

[Desktop Entry]
Actions=install-deb
Icon=dialog-information
MimeType=application/vnd.debian.binary-package
Type=Service
ServiceTypes=KonqPopupMenu/Plugin
X-KDE-Priority=TopLevel

[Desktop Action install-deb]
Name=install-deb
Exec=konsole --hold -e bash -ic 'sudo apt install %f && notify-send --expire-time=50000 "DONE"'

From now on, if one right-clicks on a .deb file in Dolphin, the context menu offers "install-deb" as one of the options. Selecting "install-deb" will open up konsole and run sudo apt install %f, where %f in this case, refers to the gcolor .deb downloaded via wget.

This is what konsole's output looks like:

[sudo] password for dkb:

Reading state information... Done
Note, selecting 'gcolor2' instead of '/home/dkb/Downloads/gcolor2_0.4-2.1ubuntu1_amd64.deb'
The following NEW packages will be installed:

After this operation, 112 kB of additional disk space will be used.

Once the install is complete, konsole will have "Finished" in its titlebar but will remain open until it is closed via the window manager. Additionally, because of the notify-send bit, a notification will be visible for the number of milliseconds specified. (I don't know why but --urgency=critical doesn't make the notification persist.)

kdialog --passivepopup "whatever text string" seems better suited for this purpose than notify-send.
