How do I remove this, I do not recall installing it, so I want it removed.
I have found in my /usr/share/applications/ App Lanucher, and I want to know how to remove it?
I can not find it. I have changed dir in the command line to /usr/share/applications$ and did "ls" and I don't see "App Lanucher" anywhere,
what am I doing wrong and how do I find it and remove it?
Xubuntu 16.04 Newly installed

I do not recall installing it, so I want it removed.
That may not be a valid reason! We don't install most software ourselves. They're part of the distro.

"ls" and I don't see "App Lanucher" anywhere,That's because the filename as seen by "ls" maybe different than the filename you and I see in our file manager! The name in the file manager is supposed to be friendlier. So something like gedit (technical name) maybe seen as "text editor" or something.

If you want to see the technical name for App Launcher, right-click on the appropriate icon in your file manager and choose to open it with a plain text editor. Look at the Exec= line.

Thanks, because the last time i tried to check it out, I clicked on it, and it went to my "panel" and it would not come off, I tried to "right click" and nothing. I tried to "right click on it" in Whiskers menu, nothing. So I am getting concerned. I just want it gone. I will try to right click and see what happens, I post a photo of what I see, But really just want it gone. Is there another way to find out what it belongs to, and just remove that?

Until it's clear what the Exec= line is, I wouldn't be in favor of removing it.

Meanwhile, edit your first post to tell people exactly which version of Linux you're using.

When I right click in Whiskers, I have 3 choices, add to favorites, desktop or panel.

I right clicked on it, in the /usr/share/applications/ and this is what I saw, and what concerns me the most is the owner "root" not sure what that means, could use some help. See attached. Thanks. 278477278478278479278480

I just checked the exe line and this is what I see:

Name=App Launcher

I found this site https://www.apt-browse.org/browse/debian/wheezy/main/i386/matchbox-panel/0.9.3-8/
It looks like something called "matchbox" I have never installed that, and never heard of it. So how do I get rid of it?

arc-
February 9th, 2018, 04:46 AM
I found this, in "apt-cache search matchbox panel"
matchbox-panel - desktop panel for resource-limited systems
matchbox-panel-manager - panel manager for matchbox-panel
So now my question is:
How did this get on my comp, as I did not or do not remember installing it.
What's the best way to get rid of it?
Is it attached to something else I installed?
Can I just remove and purge it?
Thanks again for your help.

You've most likely installed it somewhere along the line as a dependency
What does this tell you...

apt policy *matchbox*

The "App Launcher" is installed by matchbox-panel.

glen@Xubarty:~$ dpkg -S /usr/share/applications/mb-applet-menu-launcher.desktop
matchbox-panel: /usr/share/applications/mb-applet-menu-launcher.desktop

Uninstall matchbox-panel.

sudo apt remove matchbox-panel
Then cleanup...

sudo apt update
sudo apt autoremove

Please wait until a Xubuntu user comes along before removing anything.

I have Xubuntu 16.04.3 in a KVM and I don't have any "App Launcher". So it's clearly non-standard, and installed by you or by someone with admin access to your system.

Just because something is owned by root isn't reason to panic. Check out the ownership of other applications.

zgrep -i matchbox /var/log/dpkg.log*may show when it was installed if you have a relatively new system.

By the way, it doesn't seem to be anything nasty:

It was installed on 2 Feb, and it was half-installed, then unpacked, and then half-configured, then installed.

When you uninstall the package "matchbox", the other packages installed as dependencies remain installed.
There is no harm to leave these packages but it is considered good house keeping to every now and then run....

From man apt

autoremove
autoremove is used to remove packages that were automatically installed to satisfy dependencies for other packages and are now no longer needed
as dependencies changed or the package(s) needing them were removed in the meantime.

I re-ran it with quotes and it was the same.
I have a question, if you look at the attached photos, It looks like it is on the system, somehow.
So does this mean that it is not installed, but only or maybe part installed.

If "apt policy *matchbox*" shows "(none)" for all packages then nothing is installed and you should no longer have "App Launcher" in your menu.

I see similar output for "zgrep -i matchbox /var/log/dpkg.log" where I have been installing and uninstalling matchbox packages while testing.

This is just an apt log and not sure but things like "status half-configured" "status half-installed" may just be logs of the install process while waiting for other dependencies to install.
Bottom line is if ...

apt policy matchbox-panel
shows "(none)" then matchbox-panel is not installed and "App Launcher" should not be showing in your xfce menu.

The replies have been a bit long winded to give you some understanding of the process
rather than just tell you to run a couple of commands.

Thank you for helping and explaining, I have learned more about the command line.
