removing vlc inside whonix-gateway leading to chaos

as we dont use whonix gateway to watch/download anything from the internet i thought it would be good idea to remove vlc from there , but removing vlc leaded to chaotic state which i dont understand what is the linkage between it and the rest of the process:-

    user@host:~$ sudo apt-get remove vlc

Do you want to continue? [Y/n]

this is what has been remained from the gw (i installed leafpad manually):-

the bright side of this step is that gw is still giving tor connection to the ws and im browsing TBB like nothing happened. (no lost connection)

Unfortunately, nothing can be done about this. (Besides replacing all KDEish applications. But it was decided against that in this thread:

It’s due to Debian package dependencies. It’s explained in this thread:

it doesnt matter which GUI we use , because we need to no-GUI inside qubes.

so rationally KDEish being inside Qubes-whonix really unnecessary. (kmix , kmouth …etc)

yeah now i have remembered (package dependencies).

gui desktop environment package shall be defined as: For example kdm, anon-shared-desktop, xserver-xorg.

gui application shall be defined as: for example dolphin

It’s not about GUI vs CLI-only. Not about gui desktop environment packages

There are no gui desktop environment package in Qubes-Whonix. Only gui applications.

Try these commands by @entr0py in the other thread apt-cache --installed rdepends etc.

We’d have to get rid of all of the following packages.

sudo apt-cache --installed rdepends phonon
Reverse Depends:

So we could get finally get rid of phonon so we can get rid of vlc. (kde-runtime also has loads of reverse depends.)

kmouth is an accessibility tool. Can be removed. See:
News - Whonix Forum

Maybe look on it from this perspective:

In essence qubes-whonix-gateway is installed with apt-get --no-install-recommends inside a minimal Qubes Debian template. We can change dependencies in anon-meta-packages debian/control. Suggestions can be made there. But nothing can be done about reverse depends.
