Ubuntu – Problem installing a package

According to ubuntu manual:

ldconfig creates, updates, and removes the necessary links and cache (for use by the run-time linker, ld.so) to the most recent shared libraries found in the directories specified on the command line, in the file /etc/ld.so.conf, and in the trusted directories (/usr/lib and /lib).

So, assuming that freeverb.so is located in /home/yourUser/Download directory (folder), create folder in your home:

   mkdir /home/yourUser/myLibrary

and copy freeVerb.so library:

   cp /home/yourUser/Download/freeverb.so /home/yourUser/myLibrary

create a simple file freeverb.conf like this:

   echo "/home/yourUser/myLibrary" > freeverb.conf

Add you configuration file freeverb.conf in /etc/ld.so.conf.d directory (in this directory you can find files as example)

   sudo cp freeverb.conf /etc/ld.so.conf.d

Run ldconfig in order to configure dynamic linker run-time bindings.

   sudo ldconfig

If /etc/ld.so.conf.d doesn't exists, you can add your path at the end of /etc/ld.so.conf file.

At the end, if all went well, you can remove unnecessary file:

   rm freeverb.conf
   rm /home/yourUser/Download/freeverb.so

Those are directly the files you need to run the program. For opening Popcorn Time, just run from the extracted folder:

./Popcorn-Time

However, if you want to know where to save all those files with the other programs, a good place would be /usr/share.
So, let's say the folder where you extracted the files is ~/popcorn-time. Then, you'll have to run this in a terminal:

# Copy the whole folder into /usr/share, using recursive option
sudo cp -r ~/popcorn-time /usr/share/popcorn-time
# Create a symlink to the binary file
sudo ln -s /usr/share/popcorn-time/Popcorn-Time /usr/bin/popcorn-Time

From now on, you'll be able to run popcorn-Time on the Terminal, and it'll open.

Finally, if you want to have an icon in the launcher, create a new file in your home directory, named popcorn.desktop, and write the following in it:

[Desktop Entry]
Name=Popcorn Time
Comment=Watch torrent movies instantly!
Exec=/usr/bin/popcorn-time
Terminal=false
Type=Application
