Package: mate-tweak
Version: 22.10.0-2
Severity: normal
X-Debbugs-Cc: nrb...@gmail.com

Dear Maintainer,

please repeat the following steps to reproduce the issue:
1. Install task-mate-desktop with mate-tweak to get full MATE desktop
2. Launch mate-tweak from terminal
3. Go to Panel tab, then try to switch panel layouts using drop-down menu

Expected results:
* user is able to select any available MATE Panel layouts - one from Fedora,
GNOME, openSUSE

Actual results:
* user is unable to select needed panel layout, gets the following error
messages in the terminal:

```

['fedora', 'default', 'opensuse']

Would you suggest adding mate-media to Depends: field of mate-tweak?
Any alternative approach thinkable?

Thanks, Mike!

The problem here is caused by `mate-volume-control-applet` file location. It came from `mate-media`, you are right about this package

Problem persists even with the installed `mate-media` package.

In Debian 10 (buster) it was located in PATH - `/usr/bin/mate-volume-control-applet` (see https://packages.debian.org/search?suite=buster&arch=any&mode=path&searchon=contents&keywords=mate-volume-control-applet).

But in Debian 11 and newer it is located in non-PATH place - `/usr/libexec/mate-volume-control-applet` (see https://packages.debian.org/search?suite=bullseye&arch=any&mode=path&searchon=contents&keywords=mate-volume-control-applet). So it can't be found by `mate-tweak` (see https://sources.debian.org/src/mate-tweak/22.10.0-2/mate-tweak/?hl=78#L571 ).

My local quick and dirty hack is the following:
```

sudo ln -sf /usr/libexec/mate-volume-control-applet /usr/local/bin/mate-volume-control-applet

```

But I would suggest fixing this problem in the `mate-tweak` script - for example you can call this applet by full path - `/usr/libexec/mate-volume-control-applet`.

It is still applicable for default Debian installation without Ayatana indicators.

Hi Norbert,
(Cc:ing Martin Wimpress)

Ah, now I see more clearly.

The correct fix for mate-tweak will probably be to check both
locations (/usr/bin/ and /usr/libexec/) and execute the
mate-volume-control-applet found (with preference to /usr/libexec,
maybe).

Can you propose such a patch to mate-tweak upstream?

Thanks + Greets,

Norbert X

I'm not too familiar with the internals of the mate-tweak.

So I have reported a bug to upstream
https://github.com/ubuntu-mate/mate-tweak/issues/94 .
I hope to see Martin's actions there.

Thanks, Mike!
