Whenever I install things, it sometimes works, however, some things I install will not "exist" on my computer even though they were successfully install. For example, I recently installed tor browser, when I look it up in Menu, it is not there, when I try to run it on terminal it gives me this message:
Feb 06 19:37:40.234 [notice] Tor 0.4.2.7 running on Linux with Libevent 2.1.11-stable, OpenSSL 1.1.1f, Zlib 1.2.11, Liblzma 5.2.4, and Libzstd 1.4.4.

Feb 06 19:37:40.235 [err] Reading config failed--see warnings above.
I don't know what this means, but I think it wants me to check out configuration; which I have no idea how to do. I would like directions on how to do this and also how to fix this installing problem. Another example would be when I installed Signal, it didn't work for a while. Then one time I booted up the virtual box, it was just there.
I used # to get rid of my ip adress.

Hi 
Some apps do not show up inside the menu as other apps.
You need to run them via command line terminal or to run a custom binary file.
Recently I have been using Arduino Development App. After download, and unzip the downloaded file, we have a binary that you have to run via terminal to open the app. There is also a install.sh file that only create a launcher inside mate menu but link this to the place you have unziped the downloaded app - that is not perfect.
In case one of your app is not present inside the menu you can create a custom launcher for that this way :
make a file at this location with .desktop as extention, let's say :
/usr/share/applications/myfirstapplauncher.desktop
sudo nano /usr/share/applications/myfirstapplauncher.desktop
and paste inside this, and edit regarding your need :
[Desktop Entry]
Type=Application
Name=Launcher of my app
Exec="/opt/arduino-1.8.13/arduino" #Command to run my app
Icon=/usr/share/icons/arduino.png #custom icon file
Terminal=false #do you need to start it in a terminal ?
Categories=Development;IDE;Electronics; #optional

Do not hesitate to ask for more help !
Ok thank you, I think I was just getting unlucky with these two programs, they both work now and everything is fine, I will let you know if I have another problem similar to this. I did formerly try this and it wouldn't work but I think the installation was just off and it needed time for some reason. I know I'm not making much sense so sorry.
There is nothing to worry about
