I am using Ubuntu and when I click on a program to download Firefox asks me "What should firefox do with this file?" And in the "Open with" I would like to find a program "Package installer". The problem is - I don't know where to look for. Where is the program stored (I installed it using Ubuntu Software Center)

They are usually stored in the following folders:

/bin/
/usr/bin/
/sbin/
/usr/sbin/

If you're not sure, use the which command:

~$ which firefox
/usr/bin/firefox

If you installed the package with the Ubuntu package manager (apt, synaptic, dpkg or similar), you can get information about the installed package with

dpkg -L <package_name>

    Is it possible to do a search if I don't know exact name of the program. i'm asking because the name of the program is "Package installer", therefore I tried with "package_installer", "package-installer", "package", and I can't find it – Dantes Apr 26 '12 at 19:54

    `dpkg -l` lists all installed packages. You can use something like `dpkg -l | grep package` and than use `dpkg -L `. Nevertheless it is strange to add packages the way you are doing it. Typically this is done with the help of tools which are mostly always installed when using Ubuntu like `apt-get` or `synaptic`. – Andreas Florath Apr 26 '12 at 19:59

    @Dantes If you write `dpkg -L p` and press tab, it will show you the name of packages that starts with p installed on your system. – Quazi Irfan Jun 02 '15 at 23:11

Simply, type the command:

~$ whereis "program name"

for some applications, for example google chrome, they store it under /opt. you can follow the above instruction using dpkg -l to get the correct naming then dpkg -L to get the detail.

hope it helps

Just for an addition reference to the above answers. I can not use dpkg -L to find the correct path for cuda. See the results I got from dpkg -L

$ dpkg -L cuda
/.
/usr
/usr/share
/usr/share/doc
/usr/share/doc/cuda
/usr/share/doc/cuda/copyright
/usr/share/doc/cuda/changelog.Debian.gz

the correct path is /usr/local/cuda

$ ll /usr/local | grep cuda

lrwxrwxrwx  1 root root    8 Oct 20 18:45 cuda -> cuda-9.0/

drwxr-xr-x 15 root root 4096 Oct 20 18:44 cuda-9.0/

Btw, I did install cuda by the command of 

dpkg -i xx_cuda_xxx.deb

to find the program you want you can run this command at terminal:

find / usr-name "your_program"

If you are looking for the folder such as brushes, curves, etc. you can try:

/home/<username>/.gimp-2.8

This folder will contain all the gimp folders.

Good Luck.

If you are using google-chrome it might be inside your chrome extension, you can just remove the extension and use the downloaded & updated version (ubuntu 20.04)
